A new voltage-boosting converter, combining a charge pump and a coupling inductor, together with a passive voltage-clamping circuit which pumps part of the leakage inductance energy to the output, is presented herein. Therefore, by doing so, the efficiency tends to be flat between the minimum and rated loads, which is similar to the behavior of the KY converter. Moreover, the implementation of the passive voltage-clamping circuit for this converter with multiphase is very easy. In this paper, some mathematical derivations are given first, and second, simulated and experimental results are provided to verify the effectiveness of the proposed voltage-boosting converter topology.
