摘要: 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.

摘要: An inverter is electrically connected between a traction battery and a switch bank. The inverter includes a plurality of pairs of series connected power semiconductor devices. Each of the pairs is electrically connected in parallel with the traction battery to define a phase leg, and each of the power semiconductor devices has a body diode in parallel therewith. The inverter also includes a plurality of diodes connected in parallel with the power semiconductor devices such that only one of the power semiconductor devices of each of the pairs has one of the diodes connected in parallel therewith.

摘要: 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.

摘要: A powertrain for a vehicle may include a variable voltage converter (VVC), and a controller. The VVC may include an inductor, a bus capacitor and a flying capacitor. The controller may be configured to, in response to a power demand signal exceeding a threshold, modulate switches of the VVC such that an inductor current created by a collapsing field of the inductor is directed into the flying capacitor or the bus capacitor such that a bus capacitor voltage exceeds a flying capacitor voltage, and in response to the power demand signal dropping below the threshold, modulate switches such that the flying capacitor and the bus capacitor are coupled in parallel.

摘要: A vehicular system includes a pump, configured to circulate coolant for a traction inverter, and a controller. The controller may be configured to, responsive to each of a temperature of the traction inverter falling outside a first range or a requested flow rate of the pump falling outside a second range, operate the pump at a predefined speed, otherwise, operate the pump at a speed based on a difference between the temperature and a temperature associated with the coolant.
