Abstract
A high current interconnection system is provided which can be configured to couple a motor to an inverter. A high current interconnection system comprises a bus bar, a motor winding coupled to the bus bar, and a thermal interface. The motor winding is configured to receive a current. The thermal interface can be coupled to at least one of the motor winding or the bus bar. The thermal interface is configured to reduce a temperature of the motor winding or bus bar which the thermal interface is coupled to.
