Beschreibung
Zusammenfassung:	An apparatus, such as a motor drive or other power converter, includes a first controller circuit coupled to at least one serial communications channel and configured to transmit at least one serial communications signal including drive signals and at least one second controller circuit configured to receive the transmitted at least one serial communications, to recover the drive signals therefrom and to transmit the recovered drive signals on respective ones of a plurality of parallel channels to at least one driver circuit that drives semiconductor switches of a power converter. The first controller circuit may be included in a first module, the at least one second controller circuit may be included in at least one second module, and the at least one serial communications channel may include at least one cable (e.g. a fiber optic cable) connecting the first module to the at least one second module.
