摘要：
A space vector pulse-width modulation (SVPWM) strategy of the post-fault reconfigured dual inverter in open-end winding motor drive systems is discussed. The reconfigured dual H-bridge inverter can produce the same distribution of space voltage vectors with the conventional two-level inverters, but different switches are used to obtain these voltage vectors. A new seven-segment SVPWM strategy suppressing the deadtime effect of insulated gate bipolar transistors in the same leg is presented, and its algorithm and implementation are discussed. The proposed method is validated by simulations and experiments.
