Abstract: A power converter has a pair of series connected switches defining a phase leg, a pair of gate driver circuits that respectively provide power to gates of the series connected switches, a positive rail electrically connected with the phase leg, and a clamping circuit including a clamping switch. The clamping circuit, responsive to one of the gate driver circuits being de-energized, activates the clamping switch with energy from the positive rail to clamp a gate of one of the series connected switches associated with the one of the gate driver circuits to another terminal of the one of the series connected switches.

Abstract: A vehicle, an inductor assembly for power electronics in a vehicle, and a method of providing and cooling an inductor assembly are provided. According to one example, the vehicle is provided with an inductor assembly in a vehicle electrical system with a variable voltage converter (VVC). The inductor assembly includes a core formed from a plurality of core segments spaced apart from one another to define gaps therebetween, with each of the plurality of core segments forming an internal fluid passage extending therethrough. The inductor assembly has a winding surrounding at least one of the plurality of core segments. A fluid system is connected to the core to provide pressurized fluid to the fluid passages of the plurality of core segments to circulate fluid through the core of the inductor assembly.

Abstract: An automotive vehicle includes an electric machine, a traction battery, and a power converter. The power converter transfers power between the electric machine and traction battery. The power convert includes a switch that defines a portion of a phase leg, a gate driver circuit that provides provide power to a gate of the switch, and a clamping circuit. The clamping circuit includes a clamping switch that, responsive to the gate driver circuit being de-energized and a voltage of the gate exceeding a predetermined threshold value, conducts current from the gate to dissipate the voltage and clamp the gate to an emitter of the switch.

Abstract: A vehicle powertrain includes a direct-current (DC)-DC power converter and a controller. The DC-DC power converter includes first, second, and third legs in parallel, wherein the first leg is configured to carry a first DC current substantially equal to a sum of DC currents of the second and third legs. The controller may be configured to modulate switches of the first leg at a frequency greater than at least twice that of the second and third legs.
