用于双向功率流转换的完全数字化ZVS四开关Buck-Boost变换器的统一单周控制

A unified one-cycle control is presented to achieve bidirectional power flow operation for a four-switch buck–boost converter employing fully digitalized control. There is no need for analog comparators or digital-to-analog converters. Based on the new definition of operating modes, modulation can be unified in both the directional operations. One-cycle bidirectional power transition with fully ze...
