A compact and thermally efficient traction drive motor inverter featuring an integrated printed circuit board carrying both power circuitry and signal circuitry on separate electrically isolated layers without significant electromagnetic interference. Electrical communication with subsequent electrically isolated layers is maintained through the use of plated blind vias. Thermal efficiency is improved by utilizing a liquid cooled insulated gate bipolar transistor module with featuring internal flow balancers to optimize coolant flow.
