Abstract: A discharge circuit includes a discharge switch trigger unit, a discharge switch unit and a discharge resistor unit. The discharge switch unit is coupled connected to the discharge switch trigger unit. The discharge resistor unit is coupled connected to the discharge switch unit. The discharge switch trigger unit and the discharge resistor unit are coupled connected to a voltage output side. When the output voltage of a power supply reaches a predetermined rated limitation, an over voltage protection circuit is activated, and the discharge switch unit is turned on by the discharge switch trigger unit, then the output voltage starts to decrease through the discharge resistor unit.
