A Novel Variable-frequency Hysteresis and Space-vector Current Control Strategy for Three-phase PWM Rectifier
A novel control scheme for three-phase PWM rectifier is proposed in the paper which improves variable-frequency hysteresis-current control and space vector control due to the fact that there are common shortcomings in the traditional hysteresis controlling method.Compared with traditional current hysteresis control and space-vector control methods,the improving variable-frequency hysteresis and SVPWM control can reduce the delay of control time significantly.The Matlab/Simulink simulation results verify the theoretical analysis and provide with super advantages such as reducing harmonic pollution,lowering switching frequency,accelerating dynamic response and so on.This makes it vital to build a highly effective control system and regulate widespread application for three-phase PWM rectifier which contributes to energy conversion and bidirectional flow of electricity.
