Ping (2016) Common-mode voltage reduction for matrix converters using all valid switch states. IEEE Transactions on Power Electronics, 31 (12). Abstract-This paper presents a new space vector modulation (SVM) strategy for matrix converters to reduce the commonmode voltage (CMV). The reduction is achieved by using the switch configurations that connect each input phase to a different output phase, or the configurations that connect all the output phases to the input phase with minimum absolute

In comparison with the existing SVM methods, this strategy has a very similar software overhead and calculation time. Simulation and experiment results are shown to validate the effectiveness of the proposed modulation method in reducing not only the peak value but also the root mean square value of the CMV.
