Abstract
It is presented an inverter type motor drive device for feeding three phase AC electric power to an electric motor, the inverter type motor drive device comprising: an insulated metal substrate board on which, for each of the three phases, a plurality of power switches are mounted in straight lines in switch assemblies along a first direction; a printed circuit board on which a plurality of capacitors are mounted; and two DC power input terminals. The inverter type motor drive device further comprises three AC power output terminals, each extending through the printed circuit board while avoiding galvanic contact with the printed circuit board, and each of the three AC power output terminals comprise an elongated AC busbar, wherein a longitudinal direction of the AC busbar extends along the first direction.
