Abstract: A power converter utilizes a high frequency capacitor and a bulk capacitor coupled across the DC terminals to reduce high frequency effect and voltage overshoot, leading to space and cost savings in power converter design. Each capacitor may be physically coupled adjacent the gate driver board via clips, clamps, and/or fasteners.

Abstract: A three-phase connector carries all three phases in one connector and keeps the phases properly isolated from each other and the motor case. The three-phase connector has metal connector components that are spaced from one another and supported in a nylon over molding covering each of the connector components, except for upper and lower exposed ends of the connector components, which are each drilled and tapped to receive bolts. First and second connector components extend above and below a flange of the three-phase connector with their respective exposed upper and lower ends offset in different planes than the exposed upper and lower ends of the third connector component.
