Research on Three-phase Variable Frequency Power Source Based on SVPWM

Abstract

Abstract. The traditional SPWM method is designed for analog circuit which is difficult to keep pace with the trend of modern power source development. The Space Vector Pulse Width Modulation (SVPWM) takes advantages of higher voltage utilization rate, less output voltage distortion, lower harmonic content, easier for controlling and digitalization comparing traditional PWM control technology. Therefore, the three-phase variable-frequency power source control system is presented in this paper based on SVPWM technology.
