Claim:
1. An inverter leg for an inverter of an electric motor or generator, the inverter leg comprising a first device and a second device mounted on a substrate, wherein the first device includes a first switch, a first contact arranged to be coupled to a first terminal of a power source, and a second contact, wherein in a first mode of operation the first switch is arranged to electrically couple the first contact to the second contact and in a second mode of operation the first switch is arranged to electrically isolate the first contact from the second contact; the second device includes a second switch, a third contact arranged to be coupled to a second terminal of a power source, and a fourth contact, wherein in a first mode of operation the second switch is arranged to electrically couple the third contact to the fourth contact and in a second mode of operation the second switch is arranged to electrically isolate the third contact from the fourth contact, wherein the first device and the second device are mounted on the substrate such that a portion of the first contact of the first device that is arranged to be coupled to the first terminal of a power source and a portion of the third contact of the second device that is arranged to be coupled to second terminal of a power source are located adjacent to each other on a first region of the substrate and the second contact of the first device and the fourth contact of the second device are arranged to be coupled to a coil winding of the electric motor or generator, wherein the first device further comprises a first diode and the second device further comprises a second diode, wherein a first side of the first switch and the first diode is mounted on the first contact and the second contact is mounted on a second side of the first switch and first diode.
