Abstract: An AC/DC converter includes a rectifier circuit and a power factor correction circuit. An input port of the rectifier circuit receives an alternate current. The power factor correction circuit includes a first inductor, a second inductor, a first capacitor, a second capacitor, a first diode and a second diode. An end of the first inductor electrically connects to a positive pole of an output port of the rectifier circuit, and the other end electrically connects to a ground terminal of the output port through two parallel series routes which are bridged by the first diode. Wherein a series route contains the first capacitor and the second diode, and the other series route contains the second inductor and the second capacitor. The second capacitor is provided for parallel connecting with a loading. In this way, the input current could be controlled to increase the power factor effectively.
