Abstract :
In this paper, a new DC link power converter is proposed for induction motor drives. It consists of a three-phase adjustable AC/DC power converter as a pre-stage, a three-active-switch power converter to simplify the conventional six-active-switch inverter and eliminate the lock-out time circuit and an adaptive DC-link voltage controller to achieve the optimal DC voltage and minimize the switching frequency of the three-active-switch power converter. The simple rotor-flux-oriented control can also be implemented easily using the proposed power converter to achieve high performance. Finally a prototype circuit is constructed and some experimental results are presented for demonstration
