FAQ: What Technologies Can Efficiently and Reliably Power the Cloud's Datacenters?
Oct. 29, 2021
Learn how dedicated DC/DC power converters designed for datacenter equipment help make these power-hungry servers reliable, scalable, and capable of expansion.
With increasing demands for front-end cloud services, the back-end systems must be reliable, scalable, and capable of expansion. Dedicated DC/DC power converters in these servers employ multiphase topologies to deliver the required output current, with the switching of each phase controlled to optimize load regulation, ripple, transient response, and radiated and conducted noise emissions.
In this FAQ, we’ll review how datacenter equipment is typically powered, approaches to converting the 48V level to the level required by core processors, and how dedicated converters are configured.
Stricter guidelines imposed by version 3 of the IEC standard for harmonic current emissions push designers to embrace power-factor-correction methodologies.
The flyback topology is a versatile, widely used, switched-mode power-supply design with some interesting characteristics that brings performance and BOM advantages to many applications...
