Abstract
An inverter assembly includes a housing and a substrate disposed in the housing. The substrate includes at least a first conductive layer patterned to include an alternating current (AC) path and a direct current (DC) path. A plurality of inverter switches is mounted on the substrate and electrically coupled to the AC path and the DC path.
Claims20
An inverter assembly, comprising:
- a housing;
- a substrate disposed in the housing and including at least a first conductive layer patterned to include an alternating current (AC) path and a direct current (DC) path;
- a plurality of inverter switches mounted on the substrate and electrically coupled to the AC path and the DC path;
- and
- a cooling system including an outlet array coupled to the housing, the outlet array positioned so as to direct coolant fluid over the substrate and the plurality of inverter switches.
