ABSTRACT:
A power supply circuit, comprising a first reverse blocking transistor coupled to an AC power line; a second reverse blocking transistor coupled to the AC power line; a first inductor provided between the first reverse blocking transistor and the AC power line and configured to store energy; a first diode having a first terminal that is coupled to one end of the first inductor; a first capacitor having a terminal that is coupled to a second terminal of the first diode; and a first output terminal provided between the first diode and the first capacitor. The first and second transistors are arranged in an anti-parallel configuration and together define an AC switch.
