The Benefits of GaN in Motor Drive/Inverter Designs

Di Chen, Director of Business Development & Technical Marketing, Cambridge GaN Devices (CGD)

Although gallium nitride (GaN) has been discussed as an interesting solution for inverters and motor drives for ten years, there have been very few real applications of GaN in this sector to date. However, now that GaN has been proven in other applications, such as chargers, its value proposition is now being se

MOSFET Selection and Efficiency Measurement for AI Server Power Supplies

Marco Ventimiglia and Filippo Scrimizzi, Power & Discrete Sub-Group, STMicroelectronics

Yole predicts AI data center server power ratings will jump from 15kW to over 100kW, and the main bus voltage will increase from 400V to 800V to reduce distribution losses. Despite this, rack space and PSU form factors will remain unchanged, pressuring PSU vendors to achieve higher power density. Yole forecasts th
