Embodiments of this application provide a power conversion apparatus and a charging apparatus. The power conversion apparatus includes an AC-DC conversion circuit, a power controller, and a circulating current controller. The power controller is configured to control the AC-DC conversion circuit to convert a received alternating current into a first direct current and output the first direct current. The circulating current controller is configured to send a synchronization signal to another power conversion apparatus through a controller area network CAN bus. The synchronization signal is used to synchronize a carrier of the another power conversion apparatus with a carrier of the power conversion apparatus provided in embodiments of this application. According to the technical solutions provided in embodiments of this application, a circulating current between a plurality of power conversion apparatuses connected in parallel can be suppressed. This helps improve running stability of the charging apparatus.
