Abstract: While a voltage at a gate of one of a pair of series connected switches of a phase leg is greater than a threshold value, circuitry generates a signal with a logical value that precludes a gate driver corresponding to a gate of the other of the pair of series connected switches from driving the gate of the other of the pair of series connected switches.

Abstract: This disclosure is directed to power systems for transferring power between electrical components. An exemplary power system includes a first electrical component (e.g., an electric motor), a second electrical component (e.g., an inverter system), and a terminal block assembly adapted to electrically couple the first and second electrical components. The terminal block assembly includes an internal cooling channel configured to receive coolant for providing direct liquid cooling of the bus bar.

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 inductor for a converter of an electric machine includes a core defining a channel configured to receive transmission fluid on an outer surface of the core. Coils made of windings are wrapped on the core. The windings enclose an open side of the channel to define an oil flow passage, wherein oil flowing through the oil flow passage is in direct contact with both the windings and the core to absorb heat from the windings and the core.

Abstract: A vehicle power system has a power converter including a pair of switches and a pair of diodes all connected in series, an inverter, a traction battery including a pair of series connected battery modules collectively electrically connected between, and in parallel with, the power converter and inverter; and a controller. The controller complementarily opens and closes the switches to alternately charge the battery modules with direct current such that a magnitude of current input to the power converter remains constant.

CPC classification number: H05K7/20872
Abstract: An electrified vehicle includes an inductor having an associated arcuate deflector to redirect fluid toward inductor coils to facilitate heat transfer. The inductor may be disposed within a transmission proximate to at least one gear that distributes fluid during rotation to proximate components to provide splash lubrication. The arcuate deflector may redirect splashed fluid from between the inductor and the transmission housing toward the inductor coils. The deflector may be secured to the inductor via terminal connectors that electrically couple the inductor coils to a bus bar connected to a variable voltage converter.

Abstract: A power converter includes a plurality of switches, a transformer electrically connected between some and other of the switches, and a plurality of series connected capacitors electrically connected between the switches and an output of the power converter. A controller operates the switches such that a voltage at an input of the power converter and across each of the capacitors is same and a voltage at the output is double the voltage at the input.

Abstract: An automotive power converter may be controlled by detecting a magnitude of current output by a phase leg of the automotive power converter, selecting a mutual off time for switches of the phase leg according to the magnitude, and generating pulse width modulation signals for the switches having the mutual off time to operate the switches to transfer power between a traction battery and electric machine.

Abstract: A vehicle power system includes a traction battery, an electric machine configured to receive power from the traction battery, switching circuitry connected between the traction battery and electric machine, and including pairs of switches connected in parallel, and a capacitor connected with and between the pairs such that the capacitor shares a common terminal with each of the switches of the pairs, and a controller configured to responsive to a temperature of the traction battery being less than a first threshold, activate the switches of each of the pairs in complementary fashion at a switching frequency corresponding to a resonant frequency defined by a capacitance of the capacitor and an inductance of the traction battery to cause AC current to circulate between the traction battery and switching circuitry to generate heat within the traction battery, and responsive to the temperature exceeding a second threshold, deactivate the switches.
