    Abstract: A power electronics switching system has a power converter including switching elements respectively disposed in parallel paths. The system also has a controller that outputs switching commands for the switching elements derived from carrier waveforms and reference waveforms corresponding to the switching elements, and generates a shape for one of the carrier waveforms according to a difference in magnitudes between the reference waveforms such that the shape is of a first type responsive to the difference being greater than a first threshold and is of a second type different than the first type responsive to the difference being less than a second threshold.

    Abstract: A power inverter includes a plurality of power modules stacked in an array. A plurality of coolant chambers are interleaved with the modules. Each of the chambers includes an inlet and an outlet interconnected by a coolant path configured to circulate coolant within the chamber. Fins project into the coolant path and are configured to alter shape based on a temperature of the coolant to alter a turbulence associated with the coolant.

    Abstract: An example multilayered bus bar includes, among other things, a first conductive layer, a second conductive layer, and a third conductive layer. The second conductive layer is sandwiched between the first and third conductive layers. A polarity of the second conductive layer is different than a polarity of the first and third conductive layers.
