PROBLEM TO BE SOLVED: To provide a power conversion apparatus and machine having the same, capable of selectively suppressing harmonic noise in a frequency bandwidth.SOLUTION: The power conversion apparatus includes: a switching element; a switching signal generation section that generates a switching control signal for controlling on and off operations of the switching element; and a control section. The switching signal generation section generates a switching control signal formed from a combination of a pair of symmetrical pulse waveforms in which on and off periods relative to repetitive cycles are switched to each other. |
