Kind Code:
A1
Abstract:
Disclosed in the present invention is a power conversion circuit, for use in switching between a plurality of power supplies to supply power to a load. The power conversion circuit comprises a first switch, a second switch, and a bypass switch, wherein one of a plurality of power supplies supplies power to the load by means of the first switch and the second switch, and the bypass switch is located on neutral wires and connected in parallel to the second switch, and is configured to control the overlapping time of the neutral wires in the process of performing switching between the plurality of power supplies. According to the power conversion circuit comprising the bypass switch provided by the present disclosure, the overlapping time of the neutral wires in the power conversion process can be shortened to a microsecond level, so that the response is rapid and reliable.
