| 20110025236 | POWER CONVERSION EQUIPMENT - Power conversion equipment includes an electric power converting section that converts DC electric power to multiphase AC electric power and feeds the converted multiphase AC electric power to a multiphase AC motor. A first short-circuit section includes a first switch disposed between a first DC power supply and the electric power converting section. A second short-circuit section includes a second switch disposed between at least one of an electric power feeding section and the electric power input section in the first DC power supply, or between a multiphase AC output point of the electric power converting section and the multiphase AC motor. A switch control section controls the first switch and the second switch such that the first and second switches are prevented from being brought into the closed-state simultaneously. | 02-03-2011 |
