Non isolated ZCT DC-DC converter for high step-up, high efficiency applications using resonant PWM technique

This paper presents a new topology for DC/DC converter which satisfies the need for high gain, high efficiency, low weight and low cost for renewables application. This topology is a novel approach of Resonant PWM converters which produces high output voltage with soft switching method (ZVS). The converter can be controlled both by PWM and frequency variation method. The main characteristics of this structure are illustrated using simulation results and compared with other well-known structures.
