| titleOfInvention | Power inverter and its motor drive, air blower, compressor, air conditioner, refrigerator, refrigeration machine |
| abstract | The present invention provides a kind of power inverter, during its detection that can expand phase current simultaneously and simplifies detecting step, and controls carrier frequency to improve the performance of equipment and device.In power inverter, it is provided with：Power source diverter resistance（5）, it is arranged at dc source（1）Negative voltage side and inverter（2）Between；And bridge arm shunt resistance under each phase（6a~6c）, it is respectively arranged at leg switching elements under each phase（3d~3f）With power source diverter resistance（5）Between, wherein, to leg switching elements under each phase（3d~3f）With bridge arm shunt resistance under each phase（6a~6c）Each tie point and dc source（1）Negative voltage side between each voltage, bridge arm voltage is detected under i.e. each phase, and based on each detected value, calculate and flow into load device（9）Each phase current, and according to specific control parameter（A）Change, the carrier frequency to the carrier signal of the reference frequency as each drive signal is controlled. |
