They come in a choice of packaging and current ratings, as well as in various topologies including dual diode, full bridge, phase leg, dual common cathode and three-phase bridge.
“The devices’ high avalanche performance allows system designers to reduce the need for snubber circuits, and the body diode stability allows designs to use the internal body diode without long-term degradation,” according to the company.
To go along with the modules, there is a reference design for a 30kW three phase power factor corrector (‘Vienna‘), and module drive reference designs (SP3 and SP6LI) and boards. SiC Spice models are available.
The SiC diode module web page is here.
Vienna uses 1.2kVSiC diodes and 700V SiC mosfets, and takes in three-phase 380/400Vrms (50 or 60Hz) to produce 700Vdc. Switching is at 140kHz and control comes from a dsPIC33CH DSP. You have to sign-up with microchip for more details.
