摘要：

This study presents the improved phase disposition pulse width modulation (PDPWM) technique control for MMCs, which is flexible for fault-tolerant capability. Fault tolerance improves converter reliability, which is one of the important issues of half-bridge MMCs with considerable switching devices. In this study, MMC with a fault condition has been analyzed. So, a modulation control for the fault-tolerant method has been presented as well as described in simulation model. The proposed method bypasses the faulty SM when the malfuntioning occurs. This method does not produce interfere the reference signal and using only one single carrier form which reduces the software requirement. Simulation is contained to validate the fault-tolerant capability of the proposed modulation strategy for MMCs.
