An inverter assembly including a phase-control chamber and a direct current (DC) chamber. The phase-control chamber includes a direct current (DC) link capacitor electrically connected a control circuit board via multiple connectors. The DC chamber includes a ferrite filter fixed to a DC bus bar via a support component.

Inverter with capacitor discharge and DC bus filtering

An inverter is provided that includes a direct current (DC) bus bar assembly positioned within a DC chamber in the housing is provided herein. The inverter further includes a gate-driver circuit board included in a phase-control chamber in the housing, and an external communication interface in electronic communication with a power control circuit board and positioned in an external communication chamber in the housing. The DC chamber, the phase-control chamber, and the external communication chamber have varying levels of electromagnetic interference (EMI).

Inverter with housing chambers for electromagnetic interference (EMI) reduction

A system is shown for cooling components of an inverter. In one example, an inverter comprises a first compartment including a direct current (DC) link capacitor that is electrically coupled to a discharge resistor; and a thermal pad in contact with the DC link capacitor; a cooling system configured to circulate coolant through a housing adjacent to the thermal pad; and a noise filtering ferrite element coupled to a DC bus bar. A cooling plate may be further included between the DC link capacitor and the thermal pad and during a during a first condition when the inverter is operating, heat is transferred from the DC link capacitor to the cooling system; and during a second condition when the inverter is not operating, heat is reduced in the DC link capacitor by discharging electricity stored in the DC link capacitor via the discharge resistor.

Inverter with capacitor discharge and cooling system

Systems are provided for a cooling system for an electric vehicle. In one example, a system includes a plate arranged between separate circuit boards. The plate directly cools one of the circuit boards and block thermal communication between the circuit boards.

Systems for thermal management of a vehicle

A multiphase connector for electric powertrain systems includes a terminal block and a plug member that are, at least in part, made from electrically conductive metal. The terminal block has at least one socket surrounding a retaining spring and the plug member has at least one contact pin configured to be inserted in to the at least one socket. The plug member can be engaged with the terminal block without use of installation tools and includes one or more cable gland assembly in contact with a shield of a shielded cable.
