Gate Driver Core Optimized for SiC MOSFET Modules


Software configurable Vgs, Patented Augmented Turn-Off switching technique, robust high-noise-immunity design, advanced monitoring and fault reporting in a compact form factor facilitate conversion from IGBTs to SiC MOSFET power modules

Philadelphia, PA—AgileSwitch, LLC introduces the ASC1 (AgileSwitch Software Configurable Core) SiC MOSFET gate driver core. A family of tested reference adapter boards will provide compatibility with most SiC MOSFET modules. Applications including heavy-duty traction vehicles, auxiliary power units in trains, buses and trolleys, induction heating systems and other high-power industrial systems are rapidly moving from IGBTs to SiC power devices. The ASC1 driver core is designed specifically to facilitate this conversion.

The ASC1 driver core features configurable gate voltage and incorporates AgileSwitch’s patented, software configurable Augmented Turn-Off (ATOff) technology. ATOff addresses two significant impediments to the successful implementation of Silicon Carbide modules in high-power applications. By reducing turn-off spikes and ringing, both under normal operation as well as short-circuit (DSAT) conditions, SiC MOSFET modules can be safely operated in the higher frequencies that enable dramatic increases in power conversion density. This allows SiC MOSFET modules to be operated closer to their rated specifications, resulting in size, cost and performance improvements. The ASC1 gate driver core is designed for harsh, high-noise environments, with optional conformal coating. It is equipped with powerful diagnostic and troubleshooting tools and it continuously monitors critical parameters, such as temperature and DC link voltage.
