| Abstract |
This paper deals with the control of a three-phase Voltage-source current-regulated boost type PWM rectifier. The control scheme uses a synchronously rotating reference frame to control the input current on the rectifier. Given the non-linear nature of the DC link voltage dynamics, The square of the DC link voltage is defined as the controlled variable, to cancel the non-linear nature of the DC link voltage dynamics. Additionally, feed-forward or load compensation is used to overcome the time varying load and improve the transient response of the voltage control loop. The voltage controller and the feed-forward compensation set the reference d-axis current demand to balance the active power. The system including the vector control of the current control loops, the PWM strategy, the DC link voltage controller and the rectifier modelling has been simulated and an experimental rig has been set up to validate the control approach. |
