Abstract

This paper presents two novel soft-switched high-frequency high-efficiency, fast transient response 12 V voltage regulator (VR) topologies-the phase-shift buck (PSB) and the matrix-transformer phase-shift buck (MTPSB)-for high current applications. They improve efficiency at high switching frequencies and also feature very simple magnetic structures. For future high-frequency, high-current 12 V VRs, PSB and MTPSB converters are the cost-effective solutions. Experimental results confirm the theoretical prediction.
