A SYSTEM FOR DRIVING A MOTOR BY A PULSE WIDTH MODULATION INVERTER |
摘要 |
A system for driving an alternate current motor including a pulse width modulation inverter having the two-range driving characteristics, wherein the motor is driven by the pulse width modulation output having a simulated sine wave form at the speed lower than the base speed of the motor and by the pulse width modulation output having a rectangular wave form at the speed higher than the base speed of the motor. |
