1. A single stage AC/DC converter comprising:

  • a rectifier to rectify an input AC voltage and output the input AC voltage from a first input node and a second input node to a first output node and a second output node;

    an input capacitor connected between the first and second output nodes to store a rectified voltage and output a constant voltage;

    a transformer unit to transform the voltage, which is received from the input capacitor, and transmit the voltage from a primary side to a secondary side; and

    a power factor correction circuit to correct a power factor of a circuit,wherein the power factor correction circuit comprises;

    a first auxiliary diode having one terminal connected with the first input node;

    a second auxiliary diode having one terminal connected with the second input node;

    an auxiliary winding inductor connected between opposite terminals of the first and second auxiliary diodes and the first output node, and coupled with the transformer unit; and

    a first input inductor connected between the auxiliary winding inductor connected with the first output node and the input capacitor.
