<P>PROBLEM TO BE SOLVED: To obtain a power converter for effectively utilizing a function for controlling an output voltage from a DC voltage power supply and achieving an optimal operation depending on a situation. <P>SOLUTION: The power converter is provided with an optimal voltage instruction generator 7 for outputting an optimal DC voltage instruction VDC* and a modulation rate kmod so as to minimize the sum of losses in a three-phase power converter 1 and a load 2. A variable voltage power supply 4 outputs a voltage controlled by the DC voltage instruction VDC*. The three-phase power converter 1 is controlled by a switching operation at the modulation rate kmod. <P>COPYRIGHT: (C)2007,JPO&INPIT |
