Claim 5:
6. A multilevel converter system in accordance with claim 1, wherein said multilevel converter comprises a bus capacitor electrically connected in parallel with said plurality of first switches and said plurality of second switches, wherein said multilevel converter further comprises a flying capacitor electrically connected in series with said plurality of first switches and electrically connected in parallel with said plurality of second switches, wherein said at least one electrical component comprises an auxiliary switch and a resistor, wherein said auxiliary switch and said resistor are electrically connected in parallel with said flying capacitor, wherein said auxiliary switch is turned on when the short-circuit condition is detected and an absolute value of a difference between a voltage across said bus capacitor and a voltage across said flying capacitor is less than a predetermined threshold, and wherein the predetermined threshold is less than a device breakdown voltage of said plurality of first switches.
