Abstract

This paper proposes a novel variable speed motor drive, a wound field synchronous motor (WFSM) drive integrated with a Z-source inverter (ZSI). The proposed WFSM is a nonpermanent magnet machine and employs two field coils as dc field mmf sources. On the other hand, the ZSI has an impedance network that consists of two dc reactors and two capacitors. In the proposed drive, the two field coils of the WFSM act not only as dc field mmf sources but also as dc reactors in the ZSI, resulting in size and cost reductions in the drive system. In order to achieve voltage boost-up and field current controls simultaneously, the control algorithm for this integrated system is examined. Experimental results using a test drive system show that the proposed drive under the proposed control works properly.
