The necessity of having a stiff voltage source irrespective of any perturbations in the input and load conditions with parametric uncertainties is the demand of the next generation switch mode power supplies for low/high power applications. In the presented paper, the analysis of non-ideal tri-state boost (TSB) DCDC converter for low power circuits is explored with detailed modeling of small signals and stability analysis. The tri-state boost (TSB) boost DC-DC converter with steady state and transient state performance is also presented. The PI controller provides less phase boost in the phase plot of the converter which can be mitigated by Type II compensator with an extra pole at the origin. The boost DC-DC converter topology possesses a shifted right-half plane (RHP) zero in its small signal control. With the Type II compensator (T2C), there is an added degree of freedom in terms of poles. The absence of RHP zero in the TSB DC-DC converter allows the controller to attain a larger bandwidth under the closed loop condition, maintaining a smooth response. The presented system performance and results are validated using MATLAB/SIMULINK software.

DC-DC converters are used in the variety of industrial processes, one of which is the battery charging for electric vehicles (EVs). Since, these converters are more prone to switch faults and to guarantee reliable operation fault tolerant converters are used. The paper presents the design of a 2.2 kW fault-tolerant interleaved buck converter. Additionally, it suggests an algorithm that can identify any switch defect within one switching cycle and adjust the gains to distribute the entire current equally among the healthy legs to provide constant current. In order to have the least amount of ripple in the output voltage and output current, it also updates the phase shift of healthy legs using phase selector. A PI control is implemented along with fault tolerant control which not only avoids sharp overshoots and undershoots but also input disturbances and load variation by adjusting the duty of each leg. The proposed scheme has been analyzed and simulated in MATLAB SIMULINK.

Photovoltaic (PV) power generation is vastly dependent on solar irradiance and temperature conditions. In this paper, the temperature is chosen at standard test condition (STC) i.e., $\\boldsymbol{T}=\\mathbf{25}^{\\circ}\\mathbf{C}$, whereas variable irradiance is considered for power flow management. The maximum power point technique (MPPT) algorithm is implemented to concur optimal power from solar photovoltaic array, which is fed via the dc-dc boost converter to a variable dc loading system. A single stage switched boost inverter (SBI) is used for high gain dc-ac power conversion. The SBI is used to enable the ac loads for the operation at high voltage gain with 72 V dc bus. A battery energy storage system (BESS) is integrated and the performance of battery is measured in terms of state of charge (SOC) under different irradiance conditions. The bidirectional converter serves to regulate dc bus voltage whilst maintaining the power balance during deficit and surplus PV power generation conditions. Simulation results are provided to verify proposed microgrid network and power flow management. The results are in good agreement with theoretical analysis.

This paper presents a study on the field-oriented control (FOC) technique to control a traction permanent magnet synchronous motor (PMSM) drive for electric vehicle (EV) application, using wide band gap (WBG) devices. The FOC method is implemented to control the PMSM drive, which includes the PMSM motor and the SiC-inverter. The use of WBG devices in the inverter provides advantages such as highpower density, compact size, high switching operation and improved efficiency. The study includes simulation results of the FOC method, which shows improved dynamic response and reduced losses. To examine the robust performance of the system the EV traction motor is subjected to operate in three driving modes of vehicle i.e, acceleration, cruising, deceleration and in dynamic mode under off load and loaded condition. The overall functionality of the model under steady state and dynamic mode is simulated and verified in MATLAB-Simulink. Overall, the study shows the potential of using WBG devices in PMSM drives for EV applications to achieve improved performance and efficiency.

Multiport converters (MPC) design is promising from the point of view of centralized control and compact packaging. The basic bidirectional switching cells present several possibilities for constructing a multiport converter. This paper discusses a technique which is termed as switched-boost action, it produces two controlled ports using time-multiplexing of switches. This technique permits regulation and control of all the outputs while utilising comparatively fewer switches. An alternative to traditional DC-DC topology, multiple-output converters with a single input source are now being researched in order to increase power density in small powered multiload appliances. With the help of a switched boost MPC, a solar panel with battery storage system and household loads are connected. The battery is connected to the 12 V bus. The converter's functionality is tested with solar PV, which feeds a 12 V battery and a 36 V load bus. The converter automatically switches to a mode in which the 12 V battery powers the loads on the 36 V bus when solar power is absent.

DC-DC converters are one of the most important and challenging subsystems in charging systems. The reliability of the system has always been an issue because of the failures of the semiconductor switches. The paper presents the design of a 1kW fault-tolerant interleaved buck converter for battery charging applications. It also proposes an algorithm for detection of fault in any of the switches and uses a redundant leg-based topology so that the converter functions like the prior fault condition. The algorithm makes use of the digitally implemented circuit and hence does-not affect the cost of the system much. A modified PI control which works along with fault detection and control scheme is implemented to charge the battery in constant current mode which do not let current and voltage ripples increase after the fault. Also, it distributes the current equally to avoid stress over a particular branch. The modified control alters the faulty phase with the redundant phase after the occurrence of the fault with the help of fault detection system. The fault-tolerant capability ensures the continuous operation of the converter even after a fault and made it suitable for electric vehicle battery charging applications.

To improve solar photovoltaic (PV) panel efficiency, maximum power point tracking (MPPT) algorithm is needed, which could help to extract the optimal power from solar PV systems. The adaptive backstepping controlling approach is presented in this paper for tracking maximum power points in PV systems. The controller is based on the Lyapunov stability theory and connects the selection of an appropriate Lyapunov function with the design of feedback control action. The reference voltages which are generated for the controller are generated through the maximum power voltage (MPV) searching algorithm. The battery energy storage system (BESS) is linked to a bidirectional converter, which governs both the DC bus voltage and the power flow from the BESS. The operation of the DC microgrid is addressed under varying irradiance changes. Further, the impact of ripple current on the battery heating and its performance are discussed. MATLAB/Simulink software is used to simulate and validate the effectiveness of a BESS-enabled isolated solar PV-based system.

This article presents the time-domain characterization of semiconductor open-circuit switch faults (OCSFs), such as an open switch with a healthy diode and switch–diode pair open for the H-bridge power cell. The inverter fault signatures under diagonally opposite open switch fault conditions with a healthy diode are approximately similar; therefore, this article presents a detection algorithm with a unique identification of each faulty switch within the H-bridge power cell. The proposed algorithm is also designed to detect and identify multiple OCSFs. The nonideal characteristics of semiconductor switches are considered for the identification of switch faults. The well-known unipolar sinusoidal pulsewidth modulation technique is used for the switching of semiconductor devices for the single power cell. The mathematical expressions have also been derived to find out the effect of the switch fault using a double Fourier integral solution and the switching states. The analytical expressions have been developed for the switched output voltage waveforms under ideal switching conditions. The behavior of the switch faults has been analyzed using inverter output voltage, load current, and total harmonic distortion of the pulsewidth-modulated inverter output voltage.

The electric vehicles (EVs) are occupying the transportation sector at pace and it is expected to surpass the fuel-based vehicle in the upcoming decade. One of the major hurdles for EV is the requirement for multiple fast charging stations to meet the demand of charging of the EV. Thus arises the requirement for fast chargers that could satisfy the demand for better mileage and shorter span of charging. The proposed article is on multiport output series resonant interleaved DC-DC converter with unidirectional power flow capability of different ports with particular voltage level. Having a multiport structure reduces the requirements of components resulting the cost and volume of the system decreases in comparison with the same number of individual chargers. A control method using pulse width modulation and frequency modulation is obtained to control the output voltage and power for the three port converters. The interleaved output of the three ports helps to obtain low ripple peak current for high frequency (HF) transformer secondary side and high charging current obtained. A 3.3kW three-port output interleaved DC-DC converter has been designed and simulated in MATLAB simulation software for variable input voltage and ZVS soft-switching is achieved for wide range of input voltage.

The fault incidence possibility in power conversion system increases due to increase in number of power semiconductor devices. The converters used in the system must be fault tolerant for its continuous operation and reliability. The interleaved multiphase converters have many advantages over the conventional converters with respect to input/output current. In healthy condition, the output of three-phase interleaved buck converter (IBC) contains high frequency and smaller magnitude current ripple. Whereas, due to open-circuit faults in IBC the output current ripple magnitude increases and also small frequency ripple injected in the output current, resulting the quality of the output performance parameters degrade. In order to detect and diagnose the faults, a fast fault detection and identification algorithm is required. This research article proposed an algorithm to detect and localized the open-circuit switch faults (OCSFs) in a three-phase IBC. Simulation results validate the capability of the proposed fault detection and identification algorithm.

This paper proposes the technique to standardize 48V DC power line for homes and offices, energy storage systems (ESSs) are also integrated with solar photovoltaic (SPV) sources to control the effect of intermittency and periodicity. Battery acts as an energy buffer when SPV system could not meet the requirement of load demand. It is well known that SPV provides DC power and stores in ESS, so both of them are integrated to the DC bus. With the help of power electronics step down converter, the 48V DC bus is stepped- down to 24V which is used to power the low voltage devices like laptop, desktop, LEDs and TVs. As some appliances works on AC input, thus, with the help of power inverter 48V DC boosted up to 230V AC to meet the required voltage level. This paper further explains the model in Simulink which consists SPV array system with battery energy storage device. The DC bus uses DC-DC converter, an inverter and a bidirectional converter for charging/discharging of ESS. A Maltab/Simulink platform is used to validate the feasibility of 48V DC power line with ESS under varying irradiances.

A MATLAB SIMULINK based model is developed for the grid connected two stage PV-system using inverter. From the PV panel maximum power needs to be drawn and injected to the grid in a grid connected photovoltaic system. Different MPPT topologies and control methods are available in literature. By using the Perturb and Observe MPPT algorithm in this paper, from the photovoltaic panel maximum power is obtained. To the inverter from the photovoltaic module, a DC input voltage is fed and a controlled AC output power is obtained by adjusting Id and Iq.

In recent years, renewable sources of energy have witnessed a steady rise in their integration into the electrical utility system due to the concept of microgrids. A dc microgrid connected with both types of loads, i.e., ac and dc loads are presented. In this paper, an isolated dc microgrid system is proposed, which consists of a 5-level cascaded H-bridge multilevel inverter (CHB-MLI) with LC filter for ac loads. This microgrid also consists of 48V and 72V dc buses for dc loads with different ratings. The total harmonic distortion (THD) of the inverter output is computed using the MATLAB/Simulink FFT analyzer and the losses in the system have been calculated.

This paper presents the complete comparative analysis of advanced DC-DC converters (ADDCs), namely Luo, SEPIC and ZETA converter by considering the overall procedure for implementation of control and optimum design of standalone solar water pumping system (SSWPS). The intended system of water pumping is modelled and designed in such a way so that the overall performance even under the dynamic conditions are not affected. The ideas of designing passive components are presented in the paper such that the operation remains in continuous conduction mode (CCM) even at lower sun radiation. The INC-MPPT algorithm is used for optimal power generation from solar photo-voltaic (SPV) array. In order to shun the VSI’s switching losses due to high frequency switching a proper electronic commutation circuitry for PMBLDC motor is employed. The efficiency comparison of the intended system under similar duty cycle conditions for the three ADDCs is demonstrated by the simulation results using MATLAB/Simulink software.
