Hybrid energy systems are becoming increasingly popular due to limited supply of fossil fuels and conventional energy sources. Bidirectional power control is required in hybrid electric/fuel cell vehicles. Thus, hybrid electric/fuel cell vehicles have encouraged the development of bidirectional dc-dc converters. In this paper, a new bidirectional multi-port dc-dc converter with effective charging of energy storage source is presented, which leads to increased reliability. Energy sources having distinct V-I characteristics can be interfaced to the converter. The input sources and load are isolated with each other without using transformer, throughout the operation of the converter. The load voltage is regulated irrespective of the dynamics at the input and output side using Proportional and Integral controllers. The operating condition decides the working modes of the converter i.e. buck, boost and buck-boost mode. The analysis, design and simulation results of the converter proved its suitability for hybrid or renewable energy system applications.

In this paper, steady and dynamic performance of a multi-input buck–boost DC–DC converter is presented. The converter has the ability to supply energy from storage and renewable energy sources individually to the load. It maintains a constant output voltage under various transient conditions of load as well as source. It has the capability to operate in buck, boost, and buck–boost modes of operation. The mathematical model of the converter is developed, which is further used to design controllers for the converter. A laboratory prototype is developed for experimental realization of the converter. The analysis, design, simulation, and experimental results of the converter prove that it is suitable in hybrid electric or renewable energy systems application.

A multiple input non-isolated DC-DC converter with improved reliability is presented in this paper. The proposed converter can supply energy from storage and renewable energy sources independently to the load. It can work in buck, boost and buckboost modes depending on the operating conditions. It has the ability to maintain constant output voltage during transient conditions of load as well as source. PI controllers are used for generating appropriate pulse width modulated switching signals. In addition, it can also provide charging of storage type source through PV module when its terminal voltage drops below specified value. Steady state and small signal analysis of the converter using state space averaging method is also discussed. Simulation results prove that the converter can be used in hybrid electric or renewable power systems.

Multiple-input dc-dc converters are preferred where different energy sources are integrated to satisfy load demand. In this paper performance analysis of a multiple-input dc-dc converter for interfacing dissimilar energy sources is presented. The converter can supply energy from storage and renewable energy sources independently to the load. It provides isolation between source and load without using transformer. It can work in buck, boost and buck-boost modes depending on the operating conditions. The mathematical model of the converter is developed which is used to design the control strategy for the converter. The output voltage is regulated at desired value during transient conditions of load as well as source using Proportional and Integral controllers. Analysis, design and simulation studies of the converter proved that the converter is suitable for hybrid electric and renewable energy systems applications.
