摘要： An electric power supply circuit includes a diode bridge circuit (12) for rectifying an alternating current, a switching element (S) for causing a short-circuit for output power of the diode bridge circuit (12), and a PAM control section (15) for causing the switching element (S) to perform switching with a predetermined timing so that a waveform of an input current approximates to a sine wave.

摘要： An increase in a ripple voltage of a capacitor in a smoothing circuit is prevented to achieve a compact capacitor and cost reduction for capacitors in an electric power supply circuit which performs PAM control using a switching element. An electric power supply circuit includes a bridge circuit for rectifying alternating current power, a smoothing circuit which has two capacitors serially connected to each other, and a PAM control section for turning a switching element on and off at a predetermined timing. The PAM control section includes a phase difference detection section which detects a phase shift of a PAM waveform based on a change in a voltage difference between the two capacitors, and a phase correction section which corrects the phase of the PAM waveform so that an input current has a sine waveform.
