Abstract
A power supply apparatus includes a rectification circuit, a power factor correction circuit, an auxiliary boost circuit and a direct current to direct current conversion circuit. The auxiliary boost circuit includes an input contact, an output contact, a voltage detection unit, a control unit, a boost unit and a boost bypass unit. When a voltage value of a power factor correction power is not greater than a predetermined voltage value, the control unit is configured to turn off the boost bypass unit and turn on the boost unit, so that the boost unit boosts the power factor correction power and then the power factor correction power is sent to the direct current to direct current conversion circuit through the boost unit and the output contact.
