Research on novel input-paralleled output-paralleled half-bridge converter

This paper proposes an input-paralleled output-paralleled half-bridge converter based on single half-bridge converter, which is very suitable for the low output voltage and large output current application. All modules share a common capacitor-leg, that can reduce the number of main circuitpsilas capacitors and make topology simple. The traits and rules of combination converter are introduced and its model is founded. The reasons of not being current-sharing are discussed. The corresponding current-sharing control method is presented and designed, at the same time, interleaving control technology is introduced. Simulation results show that the proposed half-bridge combination topology structure and the corresponding control method are feasible, the effect of current-sharing and output performance are better. This topology has extensive application foreground.
