Claim 15:
16. A short-circuit protection circuit in accordance with claim 9, wherein the multilevel converter includes a bus capacitor and a flying capacitor, wherein the bus capacitor is electrically connected in parallel with the plurality of first switches and the plurality of second switches, wherein the flying capacitor is 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 first and second decoupling capacitors and first and second auxiliary switches, wherein said first decoupling capacitor is electrically connected in parallel with the bus capacitor and has a capacitance approximately two orders of magnitude or more lower than a capacitance of the bus capacitor, wherein said second decoupling capacitor is electrically connected in parallel with the flying capacitor and has a capacitance approximately two orders of magnitude or more lower than a capacitance of the flying capacitor, wherein said first auxiliary switch is electrically connected in series with the bus capacitor, wherein said second auxiliary switch is electrically connected in series with the flying capacitor, and wherein said first and second auxiliary switches are turned off when the short-circuit condition is detected.
