Breaking the Power Supply Efficiency Barrier to Achieve Optimization

May 27, 2020 by Wolfspeed Download PDF


As a leader in wide-bandgap semiconductor technology, Wolfspeed, a Cree company, partners with designers worldwide to build faster, smaller, lighter, and more powerful electronic systems. 

As market demands for data centers, electric vehicles (EVs), energy storage systems (ESS), uninterruptible power supplies (UPS), and portable power supplies increase, so do the demands for more efficient power source solutions. The ENERGY STAR® program, backed by the federal government, provides a simple and unbiased way to rate the energy efficiency of many electrical products including computers, data center equipment, appliances, office equipment, heating and cooling, and many building products.

When power supplies have low efficiency, the wasted energy turns into heat. To meet the demands of an increasing number of data centers, the newly launched 80 PLUS Titanium standard requires power supplies to attain up to 96% efficiency. Many power supply manufacturers are rushing to meet the high-efficiency requirements for certification, which can only be done by overcoming significant design challenges to increase efficiency, reduce switching loss, and achieve smaller overall side. 

In this Wolfspeed white paper, learn more about the design trade-offs, how to achieve optimization, and what sets Wolfspeed's C3M SiC 650V MOSFET family apart from the industry’s 650V silicon MOSFETs.
