Efficiency is one of the key parameters for battery electric vehicles since higher efficiency translates to
increased range for the vehicles, reduced weight, and cost due to the reduction of batteries in
the vehicle. The gate driver used to drive the power module is a critical component of the traction inverter, and a comprehensive design of the gate driver is essential for obtaining the high efficiency and safety of the inverter.
As part of this goal, a three−phase gate driver board SEC−SiCGDSSDC−GEVB has been designed
with a new isolated gate driver IC from onsemi, the NCV57050, which meets all the requirements of a complete gate drive for SiC modules.
Some of the features of NCV57050 are:
- Very high drive current capability
- Fast DESAT protection
- Isolated temperature measurement
- Active Miller clamp
- Wide bias voltage range
- and more
This whitepaper covers the specification, design, and test results of an SEC−SiCGDSSDC−GEVB evaluation board.
