Abstract
A protection circuit is connected between a power supply for providing a working voltage and a load. The protection circuit comprises an interface, a detecting module connected to the interface, a control module, and a switch module. The control module generates a plus width modulation (PWM) signal with a predetermined duty cycle when the interface interconnects with the load. The switch module periodically turns on and turns off based on the PWM signal with the predetermined duty cycle.
