Abstract
An integrated power module is disclosed for use with an electric vehicle. The power module includes: a motor drive printed circuit board having a bare-die semiconductor device embedded therein; and an onboard charger printed circuit board having a planar transformer embedded therein and an electrical connector. The onboard charger printed circuit board is configured to operate in a charging mode to supply a first amount of electricity to a battery of the electric vehicle. The electrical connector is configured to supply the first amount of electricity from an external electricity source and to the planar transformer.
