The embodiment of the invention provides a power conversion device and a charging device. The power conversion device comprises an AC-DC conversion circuit, a power controller and a circulating current controller. The power controller is used for controlling the AC-DC conversion circuit to convert the received alternating current into first direct current and then output the first direct current. The circulation controller is used for sending a synchronization signal to other power conversion devices through a controller area network (CAN) bus, and the synchronization signal is used for enabling the other power conversion devices to be synchronized with the carrier waves of the power conversion device provided by the embodiment of the invention. According to the technical scheme provided by the embodiment of the invention, circulation among the plurality of power conversion devices connected in parallel can be suppressed, and the operation stability of the charging device can be improved.

    本申请实施例提供了一种功率转换装置和充电装置。该功率转换装置包括AC‑DC转换电路、功率控制器和环流控制器。功率控制器用于控制AC‑DC转换电路将接收的交流电转换为第一直流电后输出。环流控制器用于通过控制器局域网CAN总线向其他的功率转换装置发送同步信号,同步信号用于使上述其他的功率转换装置与本申请实施例提供的功率转换装置的载波同步。本申请实施例提供的技术方案能够抑制多个并联连接的功率转换装置之间的环流,有利于提高充电装置的运行稳定性。
