Claim 13:
14. A short-circuit protection circuit in accordance with claim 9, wherein the multilevel converter includes a bus capacitor electrically connected in parallel with the plurality of first switches and the plurality of second switches, wherein the multilevel converter further includes a flying capacitor electrically connected in series with the plurality of first switches and electrically connected in parallel with the 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 the 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 the bus capacitor and a voltage across the 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.
