An AC to DC converting apparatus is disclosed. In the Ac to DC converting apparatus, a first adder adds an output voltage from a rectifying unit to a voltage depending on an output current from the rectifying unit. A current controller outputs a current control signal based on an added result from the first adder. A second adder adds a preset reference voltage to an output voltage from the switching unit. A voltage controller outputs a voltage control signal, and a third adder adds the output voltage from the rectifying unit to a duty reference voltage. A fourth adder adds the voltage control signal to an output voltage from the third adder. A signal limiting unit compares the current control signal with an output signal from the fourth adder, and outputs a compared result as an output signal. A PWM unit generates a PWM signal in response to the output signal from the signal limiting unit.
