Abstract: A DC to DC power converter includes switching circuitry and an LC filter. The LC filter includes a capacitor electrically connected between an inductor and coil. The inductor and coil are wound in a same direction. The coil is positioned and oriented relative to the inductor so that current from the switching circuitry flowing through the inductor and coil results in inductive coupling between the inductor and coil. This coupling increases a frequency at which a parasitic inductance and capacitance of the capacitor resonate.

Abstract: An electrified vehicle and associated inverter configured for powering two different types of external loads include first and second phase/line legs combined with a first neutral leg coupled to a vehicle chassis, and a second floating neutral leg that is not coupled to the vehicle chassis. The first/second phase legs and first neutral leg are coupled to a first receptacle configured to receive a corresponding plug to power a first load, such as a power tool or accessory. The first/second phase legs and the second neutral leg are coupled to a second receptacle configured to receive a corresponding plug to power a second load, such as a home or building having an earth grounding electrode. The inverter may include an isolation transformer between the loads and the traction battery, and/or may be configured to provide single phase, split-phase, or three-phase power for either or both of the neutral connections.

Abstract: A system for testing a phase leg of an inverter includes a load coupled to an output terminal of the phase leg. A test circuit includes a capacitor coupled between an inverter power input and a switch module operative to couple the capacitor to the load. The circuit further includes a switch operative to select a polarity of a voltage across the capacitor. The circuit also includes a pair of switching elements operative to selectively couple the first terminal to the inverter power input and the inverter power return. The components can be operated by a controller configured to selectively couple the load to the inverter power and return terminals, selectively charge and couple the capacitor to the load, and interface with the inverter to control a path of current flow through active and passive elements of the phase leg.

Abstract: A power inverter includes a plurality of power modules each having a power stage encased in a frame that defines an opening. The power modules are stacked in an array with the power stages being spaced apart to define coolant chambers interleaved with the power stages. The openings cooperate to form a manifold cavity extending along a length of the stack and in fluid communication with the chambers. A manifold insert is disposed in the cavity and extends through the openings.
