<P>PROBLEM TO BE SOLVED: To obtain a structure capable of preventing a change in temperature of switching elements even when a power factor or an output voltage of a load in an inverter circuit changes. <P>SOLUTION: The power converter has a structure in which when a current flowing through the switching elements (Su, Sv, Sw, Sx, Sy and Sz) is substantially constant, the switching elements (Su, Sv, Sw, Sx, Sy and Sz) are reversely conducted so that the switching elements (Su, Sv, Sw, Sx, Sy and Sz) may have a substantially constant temperature irrespective of the power factor and output voltage of the load of the inverter circuit (4). <P>COPYRIGHT: (C)2011,JPO&INPIT |
