摘要
In this article, a multiple switching-mode series-resonant half-bridge (SRHB) dc-dc converter is presented. The proposed multiple switching scheme changes switching modes to improve power efficiency for a wide output range, especially in the low output power range. This multiple switching scheme is composed of three different switching modes depending on the output power. The prototype was implemented using a single-chip microcontroller. With the multiple switching mode, high efficiency is achieved over an entire output power region. Experimental results on a 1.2 kW prototype are presented to confirm the performance of the proposed multiple switching scheme for an SRHB converter.
