Reverse matrix converters, which can step up voltages, are suitable for applications with source voltages that are lower than load

voltages, such as generator systems. Reverse matrix converter topologies are advantageous because they do not require additional

components to conventional matrix converters. In this paper, a detection method and a post-fault modulation strategy to operate a

converter as close as possible to its desired normal operation under the open-switch fault condition in the rectifier stage are 

proposed. An open-switch fault in the rectifier stage of a reverse matrix converter causes current distortions and voltage ripples in 

the system. Therefore, fault-tolerant control for open-switch faults is required to improve the reliability of a system. The proposed 

strategy determines the appropriate switching stages from among the remaining healthy switches of the converter. This is done

based on reference currents or voltages. The performance of the proposed strategy is experimentally verified.
