Abstract:
A discharge circuit includes an OC (Optical Coupler), a capacitor, an NPN-type transistor, and a discharge unit. The discharge circuit is parallel connected to a PFC (power factor corrector) circuit which includes a filter capacitor. The discharge unit has a MOSFET and a discharge resistor. A drain of the MOSFET is connected to a first terminal of the PFC circuit via the discharge resistor, a gate thereof is connected the anode of the capacitor, and a source thereof is connected to ground.
