Abstract: A traction powertrain system of an electrified vehicle includes a power electronics module and a controller. The power electronics module, such as in the form of an inverter, is configured to drive a traction motor with power from a traction battery via a DC-link capacitor. The controller has an on-board power source, such as in the form of a super capacitor. The controller is configured to, in response to detecting an event in which the DC-link capacitor is to be discharged, use power from the on-board power source for controlling the power electronics module and control the power electronics module to operate in a manner causing the DC-link capacitor to be discharged.

Abstract: A boost converter for a hybrid vehicle includes an inductor, a bus bar, an insulator, a temperature sensor, and a wire. The bus bar is configured to connect the inductor to a power source. The insulator is disposed over the bus bar and defines an array of orifices. The temperature sensor is configured to measure a temperature of the inductor. The wire is connected to the temperature sensor. The wire is weaved through the array of orifices such that the wire positionally alternates between opposing external sides of the insulator.

Abstract: A bi-directional variable voltage converter transfers power between a traction battery and an electric machine inverter. The bi-directional variable voltage converter includes a capacitor, two power module phase legs, and an air-gapped transformer with three windings and no more than four terminals. A first of the windings defines a first terminal and a second terminal of the no more than four terminals. The first terminal is directly electrically connected with a positive terminal of the traction battery and the second terminal is directly electrically connected with a positive terminal of the capacitor and a junction between the second and third windings. A second of the windings defines a third terminal of the no more than four terminals directly electrically connected with one of the power module phase legs. A third of the windings defines a fourth terminal of the no more than four terminals directly electrically connected with the other of the power module phase legs.
