Switches of a matrix converter are protected from potentially damaging charge-pump voltage build-up during a transition (dead) time by pulsing On (temporarily closing) any "at risk" switch during the transition (dead) time. The temporary closing of the "at risk" switch discharges any voltage build-up across a parallel coupled capacitor, which protects the at risk switch from damage or failure.
