Power protection control method

The invention provides a power protection control method and solves the problems such as high power consumption after the power protection is triggered. By the use of the power protection control method, system design is simplified, and delay time of the detection is set without an external capacitor, so that false triggering, caused by starting of the capacitive load, of the short-circuit protection is avoided, and meanwhile, short-circuit break time is long enough to ensure that full radiating of the power supply is achieved after output short circuit. In this way, reliability of the power supply is improved, and rapid starting of the power supply is ensured after fault removing. When the faults except short circuit occur to the power supply, the power supply never enters an intermittent service mode.
