<P>PROBLEM TO BE SOLVED: To provide a power conversion device that keeps a conduction loss from increasing. <P>SOLUTION: A power conversion device 100 includes three current type inverter circuits 1-3 each including one-way switches 11-28 and DC inductors 31-36 disposed between an input side terminal and the plurality of one-way switches 11-28. The input side terminals of the current type inverter circuits 1-3 are short-circuited, and output side terminals of the three current type inverter circuits 1-3 are connected in parallel. The DC inductors 31, 33 and 35 (32, 34 and 36) disposed in the three current type inverter circuits 1-3, respectively, are coupled together, so that a current moves between windings of the coupled DC inductors 31-36 according to on/off actions of the on-way switches 11-28. <P>COPYRIGHT: (C)2012,JPO&INPIT |
