Wolfspeed’s CGD1700HB2M-UNA is a half bridge gate driver board for evaluation of Wolfspeed C3M SiC MOSFET’s and modules. This board can be used in conjunction with Wolfspeed CIL boards or Evaluation kits. The board includes 2W power supplies with undervoltage protection and reverse polarity protection. Each of the two gate drive channels features over-current protection, an active Miller clamp, and separate turn-on and turn-off gate resistors for effortlessly tuning switching speeds. The board includes circuitry to read the temperature from a Negative Temperature Coefficient (NTC) resistor when available. The gate driver board also features MMCX connectors to accurately measure high-side and low-side VGS with fiber optically isolated probes such as the TIVP1 from Tektronix®.

Use the SpeedFit™ Design Simulator to design smaller and quieter industrial motor drive systems including industrial low voltage motor drives, servo drives, and compressors for heat pumps and air conditioners.
Power electronics devices are almost never working at maximum of their capabilities because of safety, reliability but even application mission profile. Our experts will demonstrate how Wolfspeed's free SpeedFit simulation tool is the perfect starting point before moving to accurate LTSpice simulations.
In this video, we’ll walk you through the press-in and press-out process for Wolfspeed WolfPACK™ silicon carbide power modules, which are available with and without pre-applied thermal interface material (TIM).
