Abstract : In this work, a new unique type DC–DC chopper with improved performance is proposed to drive back end of the electric drive system. The topology comprises of one magnetically coupled coil, three capacitors and four diodes connected to DC load. With this configuration, the conversion range is improved with less conduction losses and voltage stress during the switching interval of the converter operated with Switched Capacitor (SC) technique. Due to which the recovery of leakage energy from coupled inductor will help to lift the voltage as such power density and efficiency of the converter increases. This type of converter would be helpful for electric drive applications for smooth operation. The 30 V (DC) input voltage is lifted to 425.5 V (DC) output voltage, output power of 500 W, voltage gain of 14.28 with an efficiency of the converter of 97.34% is achieved by using lossless semiconductor devices. The step up converter is designed and developed using MATLAB/Simulink and its performance is simulated, verified and compared with different topology of converters. It proves that the developed topology of the converter is suitable for electric drive systems.
