This research explores a UPFC-like design with a modest dc-link capacitor as a regulatory device to mitigate voltage issues in LV distribution networks brought on by the effects from EV charging stations. The simulation results show that the UPFC can manage the sequence voltages utilising voltages obtained by PV integration to keep the far end load voltages within permitted voltage boundaries. In order to supply balanced power for series and shunt compensation, unified power flow controllers (UPFCs) are frequently used in transmission and sub-transmission, although they are infrequently used in distribution networks for voltage management. This paper examines the necessity of adopting PV integrated Unified Power Flow Controller to reduce energy losses in the distribution system and regulate the effects caused by EV charging

The growth and portability of health monitoring systems in hospitals and other medical facilities. The use of modern health monitoring systems is gaining attention in many nations. Internet of Things (IoT) technologies are paving the way for telemedicine to replace in-person doctor visits. This article suggests an IoT-based intelligent health system for real-time monitoring of vital signs and environmental cues to help identify patients. Heart rate sensor, body temperature sensor, ambient temperature sensor, carbon monoxide sensor, and carbon dioxide sensor are the five sensors used in this system to detect information about the hospital’s environment. For any scenario, the created scheme’s error rate is guaranteed to be no higher than a predetermined threshold (7%). sends the patient’s current health status to a portal where doctors may access it and process it for diagnosis. Prototype’s efficiency and suitability for health monitoring are both high.

Abstract In the current scenario, multilevel inverter plays a major role in heavy duty drive systems. MLI is one of the most advanced power converters for highly efficient AC output. But there is more to the requirement of number of control switches and total number of input sources which often generates more losses. This paper presents a new multilevel inverter design with limited number of control switches and with just one DC source to reduce these demerits. It uses a smaller number of Bi-directional switches. So that complexity of the circuit is reduced. Finally, an eleven-level inverter is designed and simulated using MATLAB/SIMULINK and THD reduction has been analyzed. This paper also provides a comparative statement of required components for various conventional methods.
