According to at least one aspect, a switching leg may include a leg of one or more main switches, connected in parallel with a leg including one or more auxiliary switches connected in series. The main switches may have improved conduction characteristics compared to the auxiliary switches. When switching a switching leg, one or more of the auxiliary switches may be turned ON at a short time delay before a corresponding main switch, and the one or more of the auxiliary switches may be turned OFF at a short time delay after the corresponding main switch, to provide soft-switching operating conditions for the main switch. The auxiliary switches connected in parallel to the main switches may help to move the switching losses away from main switches to the higher side of the auxiliary switches, while a substantial majority of current may still flow through main switches
