摘要： PROBLEM TO BE SOLVED: To provide a harmonic suppression circuit capable of suppressing harmonics by controlling on/off of the other switch element which is not in failure even if either one of two switch elements fails. SOLUTION: A micro controller (16) determines failure in a first switch element (8) based on on/off control of the first switch element (8) and the current detected with a second current detecting circuit (36), and determines failure in a second switch element (9) based on on/off control of the second switch element (9) and the current detected with a third current detecting circuit (37). The micro controller (16), if either one of the first switch element (8) and the second switch element (9) is determined to be in failure, controls on/off of the element not in failure between the first switch element (8) and the second switch element (9).
