摘要
This paper studies the inherent relations between sine-triangle and space vector PWM schemes for three-level voltage source inverters. It is shown that the two schemes can function equivalently through proper selection of common mode injections in the case of sine-triangle modulation, or dwell times in equivalent redundant switching states in the case of spare vector modulation. Simulation and measurement results illustrate that understanding of these relations can lead to a more efficient and flexible three-level modulator with desired or optimal performance.
