Transformer-less DIDO DC-DC converter for EV's

A transformer-less dual input dual output (DIDO) dc converter is proposed in this paper. This converter finds its application in fields of hybrid power system and hybridization of energy sources for electric vehicles. Supply of the output loads, charging and discharging of the battery / energy storage system can be made from the fuel cells (FC) or photo-voltaic (PV) which are provided as the primary source. Four switches controls the converter operation with design duties provided. Multiple output voltage levels are obtained to deliver power for electric motor and lighting loads in association with Electric Vehicle (EV) applications. The converter is simulated using MATLAB/Simulink. Simulation results validates the operability of the converter.
