一种兼容单相和三相电网的无电解电容单级电动汽车充电器

This article proposes a modular single-stage electrolytic capacitor-less electric vehicles charger with single and three-phase grid compatibility. The proposed single-stage structure inherently maintains dc charging current for three-phase grid. For single-phase grid, a phase module is reconfigured to operate as a power decoupling circuit, making battery current to be dc. Furthermore, the proposed...
