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.

Finding the Right Technology to Solve the Datacenter Power Challenge

Datacenters consume close to one percent of global electricity, a number that is only expected to grow. While increasing renewable energy contribution is a step in the right direction, global standards for energy efficiency is another area of focus that targets nearly 40 percent of datacenter operational costs due to energy consumption by servers and their cooling systems. Wolfspeed’s new 3.6 kW totem-pole PFC reference design is aimed at solving the datacenter and server power supply challenge by offering flexibility with high efficiency, lower cost, while meeting global efficiency standards.
