Abstract
Provided is a power conversion device capable of selectively suppressing harmonic noise in a frequency band and a machine equipped with the power conversion device. The power conversion device includes a switching element (13), a switching signal generation unit (23, 24) for generating a switching control signal for controlling the turning on/off of the switching element (13), and a control unit (18), and is characterized in that the switching control signal generation unit (23, 24) generates the switching control signal including a combination of a pair of symmetrical pulse waveforms having on and off periods that are interchanged with respect to a repeated cycle.
