1. A power source transfer circuit for switching among a plurality of power sources to supply power to a load, the power source transfer circuit comprising:
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, and wherein the bypass switch includes a first bypass switch and a second bypass switch, the first bypass switch includes a third solid-state switch and a fifth mechanical switch connected in series, and the second bypass switch includes a fourth solid-state switch and a sixth mechanical switch connected in series.
