Power factor correction circuit and driving method thereof
The present invention relates to a set protection circuit for when a diode short-circuit defect occurs in a power factor correction circuit of a critical conduction mode. In a conventional power factor correction circuit, an excessive amount of current flows to a switch if a diode is short-circuited so that the switch is damaged. In order to prevent damage to the switch, the present invention provides a method for stopping turn-on of the switch when a switch current is excessive.
