Circuit protection with SiC FETs in dual-gate configuration
White Paper Overview
A great deal of research has been conducted into the benefits of solid-state circuit breakers, which fall broadly into the classes of hybrid breakers and completely solid-state breakers with no mechanical parts. This article focuses on solid-state circuit breakers. Interest in solid-state circuit breakers and solid-state power controllers has grown rapidly in recent years. SiC JFETs have long been considered ideal devices for this application, given their ability to have low on-state resistance at high voltage ratings, without compromising their ability to limit current when needed.
Topics include:
- Why SiC for circuit protection
- Major applications for SiC-based circuit protection
- JFET, SiC FET and dual-gate SiC FET structures
- Solid-state circuit breaker
- Commercial aspects
In this white paper from UnitedSiC (Qorvo), we examine the use of normally-off SiC FETs in a dual-gate configuration to simplify the development of high current DC and AC circuit breakers.
