Si828x Gate Driver Boards for Wolfspeed XM3 Modules
Skyworks Si828x-based Gate Driver Board is well-suited for driving Wolfspeed’s Silicon Carbide (SiC) Field Effect Transistor (FET)-based XM3 modules, high voltage/high current modules suitable for traction inverters, industrial drive motors, EV fast chargers, uninterruptable power supplies, and more. Developed by Skyworks with support from Wolfspeed’s XM3 module team, a test report is available that details the operations of Skyworks’ Si828x isolated gate drivers and Wolfspeed’s half-bridge SiC FET XM3 module. It describes the Si828x’s robust short-circuit protection feature with the rugged SiC XM3 module, enabling the system to survive and operate well under extreme short-circuit conditions. The test report also includes the Si828x-XM3’s performance in switching loss, crosstalk, and common-mode immunity (CMTI) tests in a half-bridge configuration.

Si828x SiC FET Half Bridge Reference Design
The Si828x Half Bridge Reference Design is a design package engineers can utilize to implement a half-bridge circuit to invert a DC Link voltage to a pseudo-sinusoidal AC voltage. A half-bridge is an element of a larger system such as a single- or multi-phase inverter used in industrial motor drives, electric vehicle traction drives, solar inverters, and more. This reference design contains schematics, layout, bill of materials, and a user guide. While the board and kit are not available for purchase, the technical material will provide a design example using the Si828x family of isolated gate drivers with protection and dc-dc option. Further, this reference design has been extensively tested by Wolfspeed, and a report is available with the lab test results.
