Abstract :
In this paper, a new soft switching high step-up converter is proposed. This converter consists of two flyback transformers and one forward transformer which it is able to increase output voltage gain. Active clamp circuit in this converter not only absorb the voltage spike across the main switches due to leakage inductance but also provide soft switching condition for all switches. This converter controlled by PWM signal, so implementation of control circuit is very simple. In this paper experimental results verify the theoretical analysis.
