In this paper, a novel high-voltage gain converter is proposed, which is based on passive clamp coupled inductor, and two voltage double cells are added to extend the voltage gain. The voltage stress on the main switch is reduced with a passive clamp circuit; low on-state resistance of the main switch can be adopted to reduce the conduction loss. Furthermore, zero-current-switching turn-on is achieved...
The paper introduces a current-fed push-pull ZVS DC-DC converter topology which has some superiority in low voltage and high current situation. Compare with the traditional converter used in fuel cell power generation system, this new one can reduce the semiconductor switching losses and switching noise effectively, so a higher efficiency of the circuit conversion is obtained and the EMI noise is...
