Dual Channel Differential Isolated Half Bridge Gate Driver Board


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 is also protected against over-current. The board includes circuits to read temperature from a Negative temperature coefficient (NTC) resistor when available.

Wolfspeed in Automotive Power Systems

This webinar highlights the advantages of Wolfspeed’s SiC portfolio for the automotive market. The impact SiC can have on a variety of applications including EV drivetrain inverter, 400 and 800V battery system, etc. It also compares systems benefits and reference designs (XM3 300kW, Vepco 180k). Second section of the webinar introduces SiC in EV OBC, 400 and 800V battery system, unidirectional and bidirectional, comparing system benefits and reference designs (6.6kW 650V, 22kW,1200V). The webinar and its content is in Italian language.
