System, method, and apparatus for integrating high power density power electronics on a mobile application

A power take off (PTO) system comprising:

• an electric motor/generator;
• a power transfer element, coupled to a transmission of a vehicle, the power transfer element configured to selectively transfer torque from the electric motor/generator to the transmission or transfer torque from the transmission to the electric motor/generator based on a mode of the power transfer element;
• and
• a motor drive converter configured to transfer electric power to the electric motor/generator or receive electric power from the electric motor/generator based at least on the mode, wherein the motor drive converter comprises:
• a cold plate having a first side and a second side, the first side being opposite to the second side;
• at least one motor phase power electronics disposed on the first side of the cold plate;
• and
• a capacitor array disposed on the second side of the cold plate;
• wherein the cold plate comprises slots therethrough for a conductor to pass through the cold plate, the conductor configured to electrically couple the capacitor array and the at least one motor phase power electronics.
