NXP Semiconductors and ZF Friedrichshafen plan to collaborate on next-generation SiC-based traction inverter solutions for electric vehicles. By leveraging NXP’s advanced GD316x high-voltage isolated gate drivers, the solutions are designed to accelerate the adoption of 800-V and SiC power devices, helping extend EV range and reduce the number of charging stops while lowering system level costs for OEMs.
“We look forward to working with NXP to raise the bar for the capabilities and performance of our 800-V traction inverter solutions, which will help us achieve our goals of reducing emissions and promoting sustainability,” said Carsten Goette, Senior Vice President Electrified Powertrain Technology at ZF. “The combination of ZF’s expertise in motor control and power electronics with NXP’s GD316x gate driver family enables us to provide our latest SiC-based traction inverters with higher power and volume density, efficiency and differentiation, and provide our customers with significant safety, efficiency, range and performance improvements.”
Traction inverters are a critical component of an EV’s electric powertrain, converting DC voltage from the battery into a time-varying AC voltage, which drives the vehicle’s motor. As traction inverters now migrate to SiC-based designs, the SiC power devices need to be paired with HV isolated gate drivers to harness the advantages such as higher switching frequency, lower conduction losses, better thermal characteristics and higher robustness at high voltages, compared to previous generation silicon-based IGBT and Mosfet power switches.
The GD316x family of advanced, functionally safe, isolated, high voltage gate drivers incorporates programmable control, diagnostic, monitoring and protection features, enhanced to drive the latest SiC power modules for automotive traction inverter applications. Its high level of integration allows a smaller footprint and simplifies the system design. The outstanding capabilities reduce Electromagnetic Compatibility (EMC) noise while also reducing switching energy losses for better efficiency. Fast short-circuit protection times (< 1 µsec) in combination with powerful and programmable gate drive schemes optimize the performance of the traction inverter’s SiC power modules.
“Together with ZF, we are developing next-generation power electronics for future EVs. Our gate driver family implements a number of outstanding features to both protect and unleash the benefits of high-voltage SiC power switches, making them an ideal choice for ZF’s new SiC-based traction inverter solutions,” said Robert Li, Senior Vice President & General Manager Electrification at NXP. “This collaboration is a testament to our commitment to delivering state-of-the-art solutions that enable OEMs to achieve their EV performance and sustainability goals.”
