A new soft switching high step-up converter

In this paper a high step-up soft switching converter is presented. The proposed converter consist of a fly back transformer for increasing voltage gain and an active clamp circuit for providing ZVS conditions for all switches. In this converter the secondary of transformer is rectified by a voltage multiplier which connected series with output converter. Therefore increase voltage gain of proposed converter. This converter analysis and introduce simulation and experimental results to verify the operation of proposed converter.
