Abstract: A power conversion device according to the present invention comprises a plurality of class-D amplifiers disposed in parallel. An ON/OFF operation of a switching element of a lead leg and a delay leg of each class-D amplifier is carried out by a phase shift control, in which an auxiliary current is supplied to the class-D amplifier on the basis of a voltage difference between output terminals of an upper and lower class-D amplifiers. The auxiliary current supplements the electric current flowing between the drain and the source of the switching element. Generation of a displacement voltage dv/dt on the switching element, and a displacement current di/dt in modulation waves generated by the displacement voltage are prevented, thus preventing erroneous turn-on of the switching element in the OFF state of the other side of the leg.
