Abstract
A power supply apparatus includes a main converter, a voltage superposition circuit, a voltage detection circuit and a pulse width modulation controller. The voltage superposition circuit is electrically connected to the main converter. The voltage detection circuit is electrically connected to the main converter and the voltage superposition circuit. The pulse width modulation controller is electrically connected to the main converter and the voltage detection circuit. The main converter includes a sensing resistor. The voltage detection circuit detects a sensing voltage of the sensing resistor. The voltage superposition circuit supplies a superposition voltage to the voltage detection circuit when an output voltage of the power supply apparatus is less than a predetermined output voltage, and then the voltage detection circuit sends the sensing voltage and the superposition voltage to the pulse width modulation controller.
