Abstract
A power supply includes a transformer, a power switch, a resonant circuit, a voltage stabilization and feedback compensation circuit, and two control circuits. The power switch operates according to a first control signal so that the transformer can convert an input voltage into an output voltage. The voltage stabilization and feedback compensation circuit provides a feedback voltage associated with the input voltage and lower the feedback voltage when receiving a fourth signal having an enable level. The first control circuit adjusts the duty cycle of the first control signal and provides the fourth signal having the enable level when receiving a detecting voltage having a specific level. The second control circuit provides second and third signals for driving the resonant circuit, detects the resonant voltages of the resonant circuit, and provides the detecting voltage having the specific level when determining that the resonant circuit fails to provide zero-voltage switching.
