一种兼容单相和三相电网的电动汽车车载充电器变换器

This article proposes a voltage-source converter for an on-board electric vehicle charger, which is compatible with both the single- and three-phase (1-φ and 3-φ) grids. The classic 3-φ active ac–dc rectifier circuit is used for both the 1-φ and 3-φ connections, but a new control scheme and LCL filter are designed to address the double-line frequency power pulsation issue caused by a 1-φ grid with...
