<P>PROBLEM TO BE SOLVED: To provide a power conversion device capable of suppressing generation of electric currents leaking into a ground by on-off operations of a switching element. <P>SOLUTION: The present invention includes current detectors 31-33 for detecting an output current of an inverter circuit 4 and a noise reduction circuit 9 that runs a compensation current to cancel an electric current leaking into a ground by an operation of the inverter circuit 4. The noise reduction circuit 9 drives transistors Tr1 and Tr2 by signals for controlling on-off operations of switching elements Q1-Q6 of the inverter circuit 4 and polarities of currents detected by the current detectors 31-33. <P>COPYRIGHT: (C)2012,JPO&INPIT |
