Description
Summary:This paper proposes a new power factor correction method using an inverter-driven interior permanent magnet (IPM) motor. The proposed system realizes the high power factor of a single-phase diode rectifier by using a three-phase pulsewidth modulation inverter and an IPM motor. The proposed converter consists of a single-phase diode rectifier, a small film capacitor at the dc link (14 μF and 0.33 J/kVA), a three-phase voltage-source inverter, and an IPM motor. In the proposed system, the inverter has the following two functions: 1) It regulates the velocity of the IPM motor, and 2) it controls the source-side-current waveform. In order to obtain a unity-power-factor operation at the source side, we propose and implement a new control method that regulates the inverter output power. The proposed control method is that the inverter regulates d - q -axis current synchronous with input voltage. An inverter-output-power controller is positioned between a speed controller and a q -axis current controller. The inverter output power is regulated by a proportional-integral and repetitive controller. The maximum power factor obtained by the proposed method is 98.7% at the rated-load conditions. The superior performance of the proposed system is demonstrated by experimental results.
