An Alternate Topology for Multi Input DC/DC Converter with Performance Analysis

A single inductor dual-input single-output (DISO) DC-DC converter topology is presented in this paper.The proposed DISO topology utilises a 1-mH inductor and four switches.A 3-pulse novel PWM scheme and control strategy are introduced for efficient control.A PV source and a 36-V battery energy storage system are two sources.The 6-KW DC microgrid load consists of residential loads and electric vehicle charging station.With dropping solar irradiance, it is shown that the load demand is met by vehicle to grid transfer of power.Simulation against variation in solar irradiance from 0 W/m 2 to 1,000 W/m 2 in PV source is also done using MATLAB SIMULINK.The proposed converters performance under simulation in real time is done by using Novacor RTDS simulator along with its hardware prototype building.The converter together with the microgrid application is a rapidly emerging area of application of electronics in power system.
