摘要：

This paper proposes a pulse-voltage-injected two-phase modulation method for application to a CVCF inverter and experimentally verifies its practicality. Two-phase modulation is used in motor drives owing to its low switching loss and high DC supply voltage utilization. However, owing to its characteristic phase modulation functions, the output voltage spectrum is spread out over a wider frequency band as compared with space vector modulation. Therefore, a two-phase modulation using purely sinusoidal phase modulation functions is proposed herein. Three modulation schemes are experimentally tested, namely space vector modulation, conventional two-phase modulation, and the proposed two-phase modulation. The results indicate that the proposed two-phase modulation better minimizes the total harmonic distortion of the output voltage as well as the power loss of the output LC filter, indicating that it is optimal for CVCF inverters.
