  • Circuit protection with SiC FETs in dual-gate configuration

    SiC JFETs have long been considered ideal devices for solid-state circuit breaker and solid-state power controller applications, given their ability to have low on-state resistance at high voltage ratings, without compromising their ability to limit current when needed. In this white paper, 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.

  • New semiconductor technologies are driving higher efficiency in power conversion

    Power conversion is a common element in almost every electronic device, implemented in a variety of topologies. This white paper provides the context behind the development of new semiconductor technologies with examples given of innovative parts that are placed to provide the right mix of features for current and emerging power conversion applications.

  • Origins of SiC FETs and their evolution towards the perfect switch

    Wide band-gap semiconductors as high-frequency switches are enablers for better efficiency in power conversion. One example, the silicon carbide switch can be implemented as a SiC MOSFET or in a cascode configuration as a SiC FET. This white paper traces the origins and evolution of the SiC FET to its latest generation and compares its performance with alternative technologies.

  • Practical considerations when comparing SiC and GaN in power applications

    Silicon Carbide (SiC) and Gallium Nitride (GaN) semiconductor technologies are promising great performance for the future. SiC devices in a cascode configuration enable existing systems to be easily upgraded to get the benefits of wide band-gap devices right now.

  • SIC FETs in EV applications

    Wide bandgap semiconductors are finding applications in all types of power conversion including in electric vehicles.
