要約(英語): In this study, the authors experimentally verify the improved effects of DC supply voltage utilization by the addition of a third harmonic on pulse-voltage-injected two-phase modulation. Two-phase modulation is known for its low switching loss and high DC supply voltage utilization. However, its output voltage spectrum is spread out over a wider frequency band. Therefore, a novel two-phase modulation scheme using pulse-voltage-injection method was published previously. However, this scheme decreased the DC supply voltage utilization. To address this, the authors compare the experimental results with and without third harmonic addition and verify the effect of increasing this utilization using a three-phase voltage-fed inverter. Present results indicate that third harmonic addition improves the DC supply voltage utilization of this novel modulation scheme. Furthermore, the authors compare output voltage waveforms and spectrum, output current waveforms, and conversion efficiency to verify that the third harmonic addition does not introduce any new problems.
