Abstract

In this paper, a novel circulating current control scheme of paralleled single-phase boost-type full-bridge converters is proposed. The novel circulating current control scheme doesn't require any communication between paralleled converters. Simultaneously, the proposed circulating current control scheme improves the performance of the parallel system and reduces the circulating currents which result from the parallel connection. Based on this control scheme, not only input current shaping of each converter is improved, but also current sharing among paralleled converters is achieved. Both simulation and experimental results verified the validity of the proposed circulating current control scheme.
