摘要
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 is able to increase output voltage gain. Active clamp circuit in this converter not only absorbs the voltage spike across the main switches due to leakage inductance but also provides 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.
