要約(英語): This paper proposes a method of achieving both common-mode (CM) noise reduction and a high-voltage utilization ratio for electric compressors in vehicle air conditioners. The voltage output from the non-linear region is effectively utilized by considering both the modulator, which is based on previous studies, and the outer current controller. The proposed method consists of a simple time limiter to achieve remote-state (RS) pulse width modulation (PWM), feedback on the voltage error caused by the limiter, and a rotation direction detector to determine the voltage vector to use. As the current controller is designed using the conventional method, the proposed method is easily introduced. The effectiveness of the proposed method is compared with the conventional methods―continuous PWM (CPWM), discontinuous PWM (DPWM), and RSPWM―through experimental evaluations. The results show that the proposed method reduces CM noise by approximately 10dB in the frequency range of several hundred kHz to several MHz without additional circuits. Moreover, the proposed method has higher speed range than RSPWM and achieves the maximum voltage utilization ratio of DPWM.
