摘要： The present disclosure provides power supply apparatuses and controlling methods thereof. In some embodiments, a power supply apparatus includes a power factor correction (PFC) circuit, and a control circuit configured to control the PFC circuit. The PFC circuit includes a power inputter configured to receive alternating current voltage to be rectified, an inductor having an end coupled to an end of the power inputter, a first switching element configured to be turned on and off according to a first control signal, a second switching element configured to be turned on and off according to a second control signal, and an outputter configured to output a direct current voltage through an output capacitor. The control circuit is further configured to respectively apply the first and second control signals to the first and second switching elements such that the first and the second switching elements are alternately turned on.
