Research on the Method of Variable-Frequency Hysteresis SVPWM Current Control for Three-Phase PWM Rectifier

Abstract:

Aiming at the shortcomings of the method of conventional hysteresis current control for three-phase PWM rectifier, this paper proposes a new method, which combines Variable-frequency hysteresis current control with Space Vector Pulse-width Modulation (SVPWM) strategy. With this method, the error current can be limited in a given hysteresis loop by switching the space voltage vector of the voltage source PWM rectifier (VSR) in real time. And it can get a faster response for the current, while the frequency of the switches can be reduced. So, this method can obtain a high quality for the current control of PWM rectifier.
