摘要： A flyback power system includes a rectifier and filter circuit, a pulse width modulation (PWM) controller, a feedback circuit, a master converter circuit, a slave converter circuit, and a slave converter control circuit. The master converter circuit continuously converts power signals from the rectifier and filter circuit into first direct current (DC) power signals to drive load according to PWM signals of the PWM controller when the flyback power system powered on. The slave converter circuit converts the power signals from the rectifier and filter circuit into second DC power signals according to the PWM signals, and superposes the second DC power signals to the first DC power signals to drive the load when the load is heavy. The slave converter control circuit detects whether the load is heavy, and controls the PWM signals whether to input into the slave converter circuit according to a state of the load.
