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 DC bus for use in a power module has a positive DC conductor bus plate parallel with a negative DC conductor bus plate. One or more positive leads are connected to the positive bus and are connectable to a positive terminal of a power source. One or more negative leads are connected to the negative bus and are connectable to a negative terminal of a power source. The DC bus has one or more positive connections fastenable from the positive bus to the high side of a power module. The DC bus also has one or more negative connections fastenable from the negative bus to the low side of the power module. The positive bus and negative bus permit counter-flow of currents, thereby canceling magnetic fields and their associated inductances, and the positive and negative bus are connectable to the center portion of a power module.
