Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and apparatus for controlling AC-DC converter using a distorted triangular wave in which a PWM waveform with a low-order harmonic eliminated is prepared by comparison with a sine wave. SOLUTION: In the method for controlling the AC-DC converter to which the PWM control system applies, the distorted triangular wave in which a PWM waveform with a low-order harmonic eliminated is prepared is compared with a modulated wave formed of only a basic wave to prepare a PWM waveform and the AC-DC converter is controlled by the PWM waveform.
