摘要：This paper presents a new soft switched DC DC boost converter for high step and high voltage gainapplications such as fuel cell power conversion system, solar arrays , hybrid electrical vehicles etc. This applicationrequires high voltage gain, low conduction losses. The proposed converter achieves soft switching, zero voltageswitches are turn on in continuous conduction mode (CCM) causes low stress across the switches and zero currentswitched off the diodes which leads to negligible reverse recovery losses. The resonant pulse width modulationtechnique is achieved which allows the Lr , Cr resonance in auxiliary circuit. Also the auxiliary capacitor in the circuitreduces the cost and volume of the proposed converter and increases the efficiency as compared with the Pulse WidthModulation (PWM).Theoretical analysis and performance between PWM and RPWM technique is carried out.
