Uninterruptible Power Supplies

Future-proof your next UPS with Wolfspeed’s next-gen wide bandgap SiC semiconductors.

Overview

Improved Reliability, Cleaner Power from Wolfspeed Silicon Carbide

For mission-critical systems, a power loss can be truly catastrophic, and having a reliable backup power source is absolutely essential.

At one end of the spectrum is a simple standby battery backup that powers a home computer long enough to enable a safe shutdown. At the other end are complex, mission-critical IT systems that require customized, redundant, double-conversion uninterruptible power supply (UPS) technologies that convert AC from the grid to an DC source that keeps the batteries charged. That DC source is also converted back to AC to power 100% of the system, allowing for zero transfer time during an interruption, and since the DC source is isolated from the grid the AC signal is clean and immune from any grid instability.

Example of Wolfspeed's CRD-22AD12N reference design.

Solutions for UPS Design

UPS systems need to be able to provide reliable, clean power at any moment — and every percent of efficiency improvement means longer backup time. Wolfspeed’s Silicon Carbide MOSFETs and Schottky diodes enable 30% lower losses, has 15% system cost saving, and up to 50% higher power density than their silicon counterparts. The results are UPS systems that you can rely on when you need them the most, packing more backup power into a single enclosure, or into smaller and lighter systems for space-constrained environments.


The Numbers are on Your Side.

Wolfspeed Silicon Carbide is uniquely capable of incredible reliability and efficiency, even in the most demanding power applications.

Wolfspeed Silicon Carbide Components for UPS Systems

UPS systems must often deliver high currents with pin-point precision at a moment’s notice. That’s no easy task, but Wolfspeed’s Silicon Carbide MOSFET and Schottky diode products are up for the challenge.

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.

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.
