一种具有改进桥臂利用率的单/三相兼容PFC整流器控制方案

This letter proposes a control scheme for a single-phase (1-ph)/three-phase (3-ph) compatible PFC rectifier in electric vehicle on-board charger applications, which enables hybrid-mode control for different half-bridge legs. By utilizing the capacitor leg to take half of the return current in the 1-ph mode, the leg utilizations can be enhanced with balanced current stresses. Thereby, the 1-ph oper...
