三相電圧形3レベル変換器のためのパルス電圧重畳による二相PWM法の実機検証

抄録

Conventional two-phase PWM schemes cause harmonic voltages and currents, which are distributed over a wide frequency range however this can be a significant drawback depending on applications. To overcome this problem, the authors propose a novel two-phase PWM scheme with a pulse-voltage injection method for three-phase voltage-fed three-level converters. In this report, the authors present the validity of the proposed PWM scheme based on experimental results.
