A high step up converter, which is suitable for producing DC output renewable energy system, is proposed in this paper. A conventional interleaved boost converter obtains high step up gain without operating at extreme duty ratio through a voltage multiplier module composed of switched capacitors and coupled inductors. In addition leakage energy is recycled to output terminal, due to lossless passive clamp performance. Hence, large voltage spikes across the main switches are alleviated, and the efficiency is improved. Even the low voltage stress makes the low voltage rated MOSFETs be adopted for reductions of conduction losses and cost. Finally, the simulation circuit with 24V input voltage 600V output voltage and hardware is designed with 12V input voltage is operated to verify its performance. The highest efficiency is 97.5%.
