Abstract

An asymmetric three-level neutral point diode clamped converter for switched reluctance motor drives is proposed in this paper. The modulation method, DC-link voltage balancing algorithm, and current control scheme of this converter are presented. The proposed three-level converter is compared to the conventional asymmetric half bridge converter in terms of current ripple, cost, and power loss. The comparison results show that the proposed three-level converter has much lower current ripple and higher efficiency than the conventional two-level converter with a similar switching frequency. The effectiveness of the proposed converter is verified by simulation results.
