Abstract
A power inverter has a housing enclosing inverter electronics including power transistors electrically coupled to a DC voltage input for supplying an AC voltage output. The inverter electronics are mounted on a circuit board that is fastened to the housing and the housing has a housing wall with air vents. A heat sink including cooling fins forming air channels is mounted on the circuit board and the power transistors have a heat transfer relationship with the heat sink. A fan is mounted in a further housing wall. The heat sink is disposed so that an air stream is created through the air channels of the heat sink and between the air vents and the fan for dissipating heat generated by the power transistors.
