Zero-input-current ripple high voltage-gain DC-DC converters-A new design approach

Although numerous high-voltage-gain converters have been proposed, the input current ripple problem associated with high voltage gains is yet to be fully developed. In this paper, a systematic approach is proposed for novel power converter topologies design, to address this problem. With the proposed design guideline, a series of DC-DC converters with zero input current ripple (ZICR) and high voltage gain are developed. Then, detailed analyses are presented using a typical converter to reveal the working principle and detailed parameters design. Lastly, simulation and experimental verification is conducted, which verifies the effectiveness of this design.
