Datacenter & Server Power Supplies

SiC technology: a powerful alternative to inefficient Si components in Server Power Supplies.

Overview

Wolfspeed Silicon Carbide: More with Less

When datacenters are fitted with power supplies built with Wolfspeed’s Silicon Carbide (SiC) MOSFETs and diodes, they can deliver more computing power per square foot–with a lower electric bill.

Server & Telecom Power Supplies

A full 2% of all electrical energy in the U.S. is consumed by data centers, and that number is growing worldwide. Power supplies designed around Wolfspeed’s Silicon Carbide products improve thermal performance sufficiently to create up to 40% savings in energy costs on cooling alone. In the period from 2010 and 2020, servers running SiC devices will have contributed 620 billion kWh in energy savings. Imagine how much more energy can be saved over the next 10 years. Silicon Carbide also enables designers to meet the requirements for the 80+Titanium standard, and Wolfspeed’s products are ready to meet even tougher future standards.

How Wolfspeed Silicon Carbide Enables Offline Switching-Mode Power Supplies

Considering an offline PFC to today's 80+ highest efficiency standards or a 3 phase bidirectional grid tied active front end; maybe looking at a dc-dc switching at 1Mhz or debating going discrete or module. This whitepaper will walk through relevant SiC based system architectures to achieve such designs – all achieving higher efficiency, higher power density and lower system cost. 500W to 100kW we will consider it all with topology examples, results and design considerations.
