Scaling GaN to higher power levels in DC-DC converters and LV motor drives

This talk will focus on two board design platforms that demonstrate the scalability of GaN power solutions in different applications. For servers, you will see 4- and 6-phase IBCs with 1.6 kW and 2.4 kW output power respectively, each achieving 96.7% peak efficiency. For LV FOC motor drives, you will see a “matchbox-sized” drive with 1 kW output power using 2 paralleled HEMTs for drones, servos, and e-bikes; and a motor drive with 8 kW output power using 8 paralleled HEMTs for e-scooters and power tools. Recommendations for scaling the designs are based on a holistic system approach, targeting the highest efficiency and power density to meet customer needs.
