Abstract: A voltage converter includes a set of series connected capacitors collectively configured to provide voltage to an inverter. The voltage converter includes a switchgear including rails and switches configured to energize the capacitors with energy from the rails. The voltage converter includes interleaved inductors having respective half bridge switches configured to energize the rails. The voltage converter includes a controller configured to operate the switches of the switchgear to energize less than all of the set. The switch operation is responsive to a request to change the DC link voltage.

Abstract: A power system has a single-side-cooled power module including a contiguous five-layer substrate of two insulative layers interleaved with three conductive layers. A center one of the conductive layers is partitioned to define discrete spaced apart positive terminal and output terminal portions, and an outer of the conductive layers defines a negative terminal portion such that the positive terminal and negative terminal portions overlap. The power system also has semiconductors respectively in direct contact with the positive terminal and output terminal portions without directly contacting the other layers.

Abstract: A vehicle includes an inverter connected to an energy store having a variable output voltage and including a first pair of battery partitions. The vehicle includes a controller configured to operate a first set of switches to arrange electrical connections between the first pair such that the variable output voltage is greater than battery voltage of a one of the battery partitions. The operation of switches is responsive to a parameter indicative of speed of an electric machine electrically coupled to the inverter exceeding a first predetermined threshold.

Abstract: A power device supply includes an inverter, a converter, and a cooling system. The inverter is configured to convert direct electrical current into alternating electrical current. The converter has an inductor and is configured to amplify voltage. The cooling system has top, bottom, and intermediate cooling plates. The cooling system is arranged such that the inverter and inductor are interleaved with the plates and such that the inverter and inductor are disposed on opposing sides of the intermediate cooling plate.

Abstract: A vehicle may include an electric machine including windings having a nonzero phase offset. The vehicle may further include first and second inverters configured to drive the electric machine as a result of toggling of switches. The switches may be toggled according to respective pulse width modulation (PWM) signals. One or more gate drivers may be configured to generate the PWM signals. The PWM signals may be based on fundamental waveforms having a phase shift that is based on the nonzero phase offset of the electric machine.

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: A system for an electrified vehicle, such as a battery electric vehicle (BEV), includes an inverter connected between a battery and a motor having windings. A center-tap of the battery and a neutral-point of the windings are connected whereby the battery, the inverter, and the motor are connected in a closed circuit. The system further includes a controller configured to control the inverter to cause a circulating current from the battery through the closed circuit to thereby achieve a target temperature of the battery.

Abstract: An electric drive system includes an actively cooled inductor. The inductor is formed by winding C-shaped wire around a bobbin such that channels are defined between the bobbin and the wire. After the bobbin is installed over the core, a plastic layer is injected between the core and the bobbin. This expands the bobbin against the wire to seal the channels and also to fasten the bobbin in place. A variety of porting arrangements are proposed to route cooling fluid through the channels to cool the windings and the core.

Abstract: A power converter includes a pair of series connected switches and circuitry. The circuitry includes another switch and an optocoupler that activates responsive to changes in current through one of the series connected switches exceeding a predefined threshold. Activation of the optocoupler causes the another switch to conduct and reduce a gate voltage of the one of the series connected switches to reduce the changes in current through the one of the series connected switches.
