Even though the coupled-inductor-based high-step-down-ratio converters can achieve a higher step-down voltage gain than the traditional buck converter, their output current suffer from a high output current ripple, causing a high output voltage ripple. Therefore, a bulky electrolytic output capacitor is usually used to suppress the output voltage ripple. Moreover, the longevity of the output electrolytic capacitor is highly dependent on the output current ripple. In [6–8], a passive current ripple cancellation circuit was applied to the DC–DC converters to reduce the output current ripple. However, these literatures did not mention and analyze the situations for coupled-inductor converters. Moreover, the same concept, including analysis and design, cannot be directly applied to the coupled-inductor-based converters. Therefore, in this paper, the analysis, design, and experimental results of the current ripple cancellation circuit applied to the coupled-inductor-based high-step-down-ratio converter are given to verify the effectiveness.
