Abstract

Background

The rapid growth of the information and communications technology industry, including streaming services, cloud computing, artificial intelligence, and the Internet of Things, has introduced significant challenges for effective power management in data centers.
Developing high-performance DC/DC converters for power supplies in data centers is particularly challenging, as it requires expertise in various areas, such as circuit topology, parameter design, magnetic design, component selection, PCB layout, and even electromagnetic compatibility. Successful design demands careful and thorough consideration of all these factors.

Aims

Effective power management with high power density and high efficiency.

• Magnetic integration: Bulky magnetic components? Magnetic integration methodology is developed to shrink the footprint of the magnetic core.
• Vertical power delivery: A vertical magnetic design is proposed to facilitate the real ‘3-D’ power converter, thereby enabling high efficiency and high-power density.

Impact

• Build artistic, intelligent, efficient power converters for a sustainable world.
