Abstract

This paper presents a new common-mode voltage (CMV) suppression strategy based on open-active vectors, which reduces the CMV peak value and suppresses the common-mode spikes caused by switching. In addition, the novel open-active vector is characterized, and its common-mode equivalent circuit is established. The new modulation strategy proposes open-active vectors in place of zero voltage vectors, which reduces the peak magnitude of the output CMV by 42.3%. While reducing the CMV, the complex commutation issue of the rectifier stage and the CMV spike issue brought on by the impact of the inverter stage dead zone are both resolved by the new modulation method. The effectiveness of the new strategy is verified by simulation and experimental results.
