Abstract :
In this paper, a new control technology of doubly-fed induction machine based on the space current vector PWM (SCVPWM) strategy and current-source dual-PWM converter was presented, which can produce electrical braking torque to achieve four-quadrant operation; moreover, the reactive power of the stator side can be flexibly controlled and the harmonic distortions can be reduced by the control technology. The experimental results confirm the validity of the proposed control technology.
