Abstract

An apparatus for conversion between AC power and DC power. The apparatus includes: a first power conversion circuit having a first AC side and a DC side, at least one second power conversion circuit each having a second AC side and sharing the DC side with the first power conversion circuit, and at least one choke having a first terminal, a second terminal and at least one third terminal, wherein: the first terminal is arranged to be electrically coupled to a phase of the AC power, and the second terminal and the at least one third terminal are electrically coupled to respective same phases of the first AC side of the first power conversion circuit and the second AC side of the at least one second power conversion circuit. Moreover, the choke includes: a first common-mode choke and a first differential-mode choke, wherein: the first common-mode choke and the first differential-mode choke are electrically coupled in series via a first group of coil ends of the first common-mode choke and a first group of coil ends of the first differential-mode choke, and a second group of coil ends of one of the first common-mode choke and the first differential-mode choke are electrically coupled …
