1250 V/1700 V GaN HEMTs for NVIDIA 800 VDC Architecture

Kamal Varadarajan & Chris Lee, Power Integrations

GaN-based power semiconductors are ideal for high-efficiency power converters thanks to their superior material properties. However, very few manufacturers offer GaN HEMTs rated above 650 V. The main challenge is that GaN devices built on silicon substrates require very thick buffer layers, which adds significant pr

Addressing 400-Vdc power in advanced industrial and data-center apps

Steve Oliver, Vicor

In any operating system, distribution losses are a significant factor in overall system efficiency at every level. In the case of telecom central office applications, traditional 48Vdc systems become very expensive to install (due to increased copper cost and weight) and run (due to I2R loss) while in large da
