要約(英語): In this study, the authors experimentally verify the AC-side inductor loss of the three-phase voltage-fed inverter by evaluating the core temperature. Two-phase pulse width modulation (PWM) is renowned for its low switching losses. However, the harmonics of the AC-side voltages and currents generated by a two-phase PWM are greater than those of a three-phase PWM. Therefore, the increase in power loss due to the harmonics in the inductor connected to the AC side of the inverter is concerning. To address this issue, the authors experimentally verify and evaluate the AC-side waveforms, total harmonic distortion (THD), power dissipation and inductor core temperature, and conversion efficiency for the three-phase voltage-fed inverters with the different PWM schemes. The results demonstrate that the two-phase PWM improves conversion efficiency compared to the three-phase PWM, assuming the same THD as for the three-phase PWM. Additionally, the two-phase PWM reduces the THD compared to the three-phase PWM and reduces the power dissipation and core temperature of the inductor to the same extent as the three-phase PWM method, assuming identical conversion efficiency.
