Inverter module of an electric vehicle

A method to provide electrical power via an inverter module to power an electric vehicle, the method comprising:

• providing a capacitor;
• coupling a heat sink with a first surface of the capacitor;
• disposing a first ceramic plate with a first surface of the heat sink;
• disposing a second ceramic plate with the first surface of the heat sink;
• providing a locator having a plurality of slots;
• disposing a plurality of transistors within the plurality of slots, the locator and the plurality of transistors disposed over a first surface of the first ceramic plate and a first surface of the second ceramic plate;
• providing a laminated bus bar over a first surface of the locator;
• disposing a first input terminal at a first side of the laminated bus bar, the first input terminal at a first level with respect to the first side of the laminated bus bar;
• disposed a second input terminal at the first side of the laminated bus bar, the second input terminal at a second level with respect to the first side of the laminated bus bar;
• disposing an output terminal at a second side of the laminated bus bar;
• coupling a gate drive printed circuit board with a first surface of the laminated bus bar;
• and
• disposing a dielectric gel tray over a first surface of the gate drive printed circuit board.
