Si828x SiC FET Half Bridge Reference Design

The Silicon Labs 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 SiC FET partner Wolfspeed, and a report is available with the lab test results.

Wolfspeed WolfPACK™ Module Gate Driver Boards

Silicon Labs' Gate Driver Boards (GDB) are ideal for driving power modules from Wolfspeed, such as the Wolfspeed WolfPACK power modules. These two-channel isolated gate driver solutions feature a differential digital interface, optimized on-board isolated power supply, and user-configurable turn-on and turn-off gate resistors. Status indicator LEDs and test points make evaluation and prototyping easy. These GDB are compatible with Wolfspeed’s Clamped Inductive Load (CIL) test fixtures for controlled and comprehensive module evaluation.
