This session will cover the emerging energy storage segment and the ways Silicon Carbide (SiC) power devices can enable highest performance and lower system cost.  We will start with a breakdown of the major subsegments and technical details such as system hardware configurations, input, output voltages and power levels, key power blocks and topologies and prevalent component selections in today’s systems.  Next, we will outline the areas where Silicon Carbide devices can have an impact and describe alternative topologies, SiC component selection and outline the improvements in energy efficiency, system size, weight and cost achievable with Silicon Carbide.  Finally, we will present design approaches to optimize performance through gate drivers and gate driving design, circuit board layout techniques, choices of passive components and thermal management approaches. Adam Anders of Wolfspeed covers how to model with the SpeedFit Design Simulator™, a powerful online simulator that allows designers to quickly evaluate different power conversion topologies and Silicon Carbide devices. The platform is best utilized early in a design cycle to analyze design tradeoffs between different topologies, estimate semiconductor losses and junction temperatures, as well as identifying the best Silicon Carbide MOSFETs and Silicon Carbide diodes to use in a given design. This webinar was part of the 2021 Wolfspeed Summer Series where Silicon Carbide experts covered a number of technical sessions intended to help design engineers build devices that will power tomorrow.

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.
