An enhanced soft switching technique for an interleaved boost converter with Zero Current Switching (ZCS) and Zero Voltage Switching (ZVS) during OFF and ON conditions of the main switches, that can drive large loads operated in duty cycle greater than 0.5 is proposed in this study. In this topology, auxiliary circuit is composed of resonant tank which is used to decrease the voltage stress on the main switches and a coupling capacitor is added additionally with minimum resonance which in-turn increases the life of operation of the converter. In this model, faster switching and suitable impedance matching is achieved with reduction in auxiliary circuit reactance that has contributed much increase in the overall performance. Coupled inductor in the boosting stage helps higher current sharing between the switches. The overall ripple and Total harmonics distortions are reduced in this technique without sacrificing the performance and efficiency of the converter. A simulation module constructed using "MATLAB Simulink" illustrates the better results of the proposed converter.
