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

Advanced Current and Voltage Sensing Enables Ultra-Precise Robots

Kia Rahbar, marketing manager for isolated converters, Texas Instruments

Robots have become commonplace in industrial applications. However, up until now, their usage has been restricted to tasks that do not require the highest levels of precision. It is hard to imagine a humanoid robot being asked to attempt to thread a needle, or a collaborative robot (cobot) to handle fragile it

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

Motor Drive ICs With Performance, Protection & Bi-Directional Sensing

Llew Vaughan-Edmunds, Senior Director Product Management and Marketing, Navitas

Electric motors and drives are estimated to consume about 45% of the total electricity generated worldwide. That’s equivalent to more than 12,000 terawatt hours (TWh) per year, or about 1,000 times the total output of China’s 5 GW Xinjiang solar farm (the world’s largest), which was connected to the gr
