THREE-PHASE CHARGING AND SINGLE-PHASE CHARGING MUTUAL SWITCHING CIRCUIT AND RELATED DEVICE

WIPO Patent Application WO/2022/011532

A1

Provided in the embodiments of the present application are a three-phase charging and single-phase charging mutual switching circuit and a related device. The three-phase charging and single-phase charging mutual switching circuit comprises an alternating-current input end, a single-pole double-throw switch, a first bridge arm, a second bridge arm, a third bridge arm, and a charging circuit. The alternating-current input end comprises a first interface, a second interface, a third interface, and a fourth interface. The first bridge arm, the second bridge arm, and the third bridge arm are connected in parallel to each other. The first bridge arm, the second bridge arm, and the third bridge arm respectively are connected to the charging circuit. The first interface is connected to the first bridge arm. The second interface is connected to the second bridge arm. The third interface is connected to the third bridge arm via a normally closed contact of the single-pole double-throw switch. The fourth interface is connected to the third bridge arm via a normally open contact of the single-pole double-throw switch. Only one circuit is required to implement compatibility with three-phase voltage charging and single-phase voltage charging functions.
