ZF partners with NXP for SiC gate drivers

ZF Friedrichshafen has taken a significant step forward in the electrification of the automotive industry by integrating high-voltage isolated gate drivers from NXP Semiconductor into its latest 800V SiC-based traction inverter for electric vehicles (EVs).

The GD316x gate driver family from NXP is being utilized by ZF for their 800V traction inverters, which play a crucial role in an EV's electric powertrain. These inverters are responsible for converting DC voltage from the battery into a time-varying AC voltage that drives the vehicle's motor.

By leveraging SiC power devices from ST and Wolfspeed through long-term supply agreements, ZF has already deployed traction inverters using the GD316x SiC gate drivers on the road. This strategic partnership underscores ZF's commitment to innovation and sustainability in the EV space.

As the industry shifts towards SiC-based designs for traction inverters, the importance of pairing SiC power devices with HV isolated gate drivers becomes paramount. These drivers support higher switching frequencies, lower conduction losses, improved thermal characteristics, and enhanced robustness at high voltages, ultimately leading to increased efficiency and range for EVs.

The GD316x gate drivers, known for their functional safety and isolation features, incorporate programmable control, diagnostic capabilities, monitoring functions, and protection mechanisms. With fast short-circuit protection times and advanced gate drive schemes, these drivers optimize the performance of SiC power modules in traction inverters.

The higher level of integration achieved through this collaboration not only results in a smaller footprint but also simplifies system design, reduces Electromagnetic Compatibility (EMC) noise, and minimizes switching energy losses, all contributing to improved efficiency in EV operations.

NXP Semiconductor views the collaboration with ZF as a significant milestone in accelerating the electrification of the automotive industry. By working together, the two companies aim to create safer, more sustainable, and energy-efficient EVs for the future.

Dr. Carsten Götte, SVP Electrified Powertrain Technology at ZF, expressed excitement about the partnership, stating, "We look forward to working with NXP to enhance the capabilities and performance of our 800-V traction inverter solutions. This collaboration allows us to deliver SiC-based traction inverters with improved power density, efficiency, and safety, contributing to our goals of reducing emissions and promoting sustainability."

Robert Li, Senior Vice President and General Manager of Electrification at NXP, emphasized the joint effort in developing next-generation power electronics for future EVs. He highlighted the exceptional features of NXP's gate driver family in protecting and maximizing the benefits of high-voltage SiC power switches, making them an ideal choice for ZF's innovative SiC-based traction inverter solutions.
