双向双桥串联谐振DC-DC变换器的宽范围ZVS控制技术

For high-voltage and high-power bidirectional dc-dc converters, soft switching of all active power devices is mandatory to ensure the high efficiency and reliability. This paper describes a control technique for wide-range zero-voltage switching (ZVS) implementation of dual-bridge series-resonant dc-dc converters. The proposed control technique integrates variable-frequency modulation (VFM) and ph...
