Silicon Carbide in Grid-Tied Applications

This whitepaper will cover the many benefits of Silicon Carbide (SiC) for Grid-Tied applications ranging from 2.2 kW to over 200 kW with Wolfspeed discrete and power module products. The presenters will perform topology analysis to demonstrate the simplifications in system implementation SiC can enable with fast, efficient switching performance compared to more complex, multi-level systems used with Si technology. Next, an overview of Wolfspeed simulation tools will demonstrate how to find the right parts to meet system needs. Finally, examples will show the audience practical examples of how to implement and get started with SiC including a 2.2 kW Totem Pole PFC and 22 kW Bi-directional active front end (AFE) with discrete devices. Utilizing Wolfspeed modules, a 25 kW Bi-directional AFE using Wolfpack modules and a 200 kW Bi-directional AFE using the XM3 module will be presented. With the topics covered, the audience will understand the advantages and capabilities Wolfspeed’s SiC family can bring to their next system design.

Deciphering Data Sheets

Datasheets are technical instruction manuals for electronic components, and the information they contain helps you select the right part for your design. But datasheets vary between component types and manufacturers, which can lead to significant misunderstandings. This whitepaper will take you through a typical Wolfspeed datasheet and explain the meaning of its specs and sections.
