The anti-interference module is coupled to the secondary side and the positive-negative narrow pulse-width signal includes multiple positive pulses and negative pulses. The anti-interference module filters out the ones from the positive pulses and negative pulses of which the pulse amplitude does not reach an effective threshold, and meanwhile the anti-interference module suppress a common-mode noise caused by a high voltage transient variation at a moment when the full-controlled power switch is turned on or off. The pulse-width demodulation unit converts the filtered positive-negative narrow pulse-width signal into a driving output signal.
