Claim 8:
9. The method of claim 8, wherein operating the plurality of switching devices in the plurality of operating states such that current simultaneously flows through the at least two parallel recovery paths of the plurality of switching devices during operation of the power converter further comprises:
transitioning from the fourth operating state to the second operating state by:
turning off the third IGBT switch, thereby allowing the second parasitic inductance to discharge energy without forcing excessive voltage across the third IGBT switch; and
subsequently turning off the fifth IGBT switch, thereby allowing energy in the first parasitic inductance to remain as-is such that turning off the fifth IGBT does not cause a voltage overshoot across the fifth IGBT.
