Claim 7:
8. A multilevel converter system in accordance with claim 1, wherein said multilevel converter comprises a bus capacitor and a flying capacitor, wherein said bus capacitor is electrically connected in parallel with said plurality of first switches and said plurality of second switches, wherein said flying capacitor is 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 first and second decoupling capacitors and first and second auxiliary switches, wherein said first decoupling capacitor is electrically connected in parallel with said bus capacitor and has a capacitance approximately two orders of magnitude or more lower than a capacitance of said bus capacitor, wherein said second decoupling capacitor is electrically connected in parallel with said flying capacitor and has a capacitance approximately two orders of magnitude or more lower than a capacitance of said flying capacitor, wherein said first auxiliary switch is electrically connected in series with said bus capacitor, wherein said second auxiliary switch is electrically connected in series with said flying capacitor, and wherein said first and second auxiliary switches are turned off when the short-circuit condition is detected.
