<P>PROBLEM TO BE SOLVED: To provide a power conversion device that implements responsive optimum control of an inductive load by suppressing harmonics of the inductive load while suppressing resonance by an LC filter. <P>SOLUTION: The power conversion device includes a control section 100 for controlling an inverter section 12 on the basis of a voltage V<SB POS="POST">L</SB>across a reactor L detected by a voltage detection section 101. The control section 100 controls the inverter section 12 such that a transfer characteristic of an input voltage of the inverter section 12 to a DC voltage from a diode bridge 11 is an attenuation characteristic by a phase lead element and a second order lag element connected in series, and an attenuation coefficient ζ of the transfer characteristic of the input voltage of the inverter section 12 to the DC voltage from the diode bridge 11 is set greater than one. <P>COPYRIGHT: (C)2013,JPO&INPIT |
