要約(英語): Three-phase voltage-fed inverters operated by a two-phase pulse width modulation (PWM) scheme offers relatively high ac voltage, low switching times, and low switching losses in comparison to that operated by a three-phase PWM scheme. However, the harmonics involved in the ac-side voltages and currents produced in the two-phase PWM scheme are distributed over a wide frequency range, which causes acoustic noise from loads. To overcome these problems, the authors proposed a novel two-phase PWM scheme in which the harmonics appear in a frequency range as narrow as that in a conventional three-phase PWM scheme. In this paper, the authors compare the acoustic noise when various PWM schemes, including the proposed PWM scheme, are applied to three-phase voltage-fed inverters.
