Abstract
The present invention discloses a power source transfer circuit for switching among a plurality of power sources to supply power to a load. The power source transfer circuit includes a first switch, a second switch and a bypass switch, wherein one of the plurality of power sources supplies power to the load via the first switch and the second switch, and wherein the bypass switch is connected in parallel to the second switch on a neutral line and is configured to control neutral overlapping duration during switching among the plurality of power sources. The power source transfer circuit including a bypass switch provided by the present disclosure can reduce the neutral overlapping duration to microseconds during power source transfer, so as to realize fast and reliable response.
