Abstract

To overcome the drawbacks of the traditional active switched inductor (A-SL) based DC/DC converter, a family of improved A-SL based converters was proposed. There are three topologies, namely the Type-I converter, the Type-II converter and the Type-III converter. Type-I converter was established by integrating the zero current ripple structure with the traditional A-SL converter, which not only overcome the large input current ripple and floating ground disadvantages of the traditional A-SL based converter, but also enhance the voltage gain. Through adding the passive clamping circuit on the Type-I converter, the Type-II converter was obtained. Due to the clamping circuit, the voltage resonance problem existing in the A-SL based converters was alleviated. In addition, the voltage gain was further increased. However, these merits were at the cost of the floating ground. The Type-III converter with the feature of common ground was developed using the same amount of circuit components as the Type-II converter. It possessed all the superiorities of the Type-I and Type-II converters. The comprehensive operation analysis and key specification calculations were carried out for the Type-III converter and a comparison study involving the proposed converters was also implemented. Finally, a 1kW, 40V/400V experimental prototype of the Type-III converter was established to verify the accuracy of the theoretical analysis and effectiveness of the proposed converters.
