Bare Die Silicon Carbide MOSFETs

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.

This whitepaper 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 (SiC) devices can have an impact and describe alternative topologies, Silicon Carbide (SiC) component selection and outline the improvements in energy efficiency, system size, weight and cost achievable with Silicon Carbide (SiC).  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.

The latest innovations in Silicon Carbide make it easier than ever to meet or exceed design requirements across the entire power spectrum. In this whitepaper, Wolfspeed will demonstrate how to achieve scalable high power systems using Wolfspeed’s entire product portfolio, from discrete packages to power modules. Understanding paralleling and interleaving best practices at both the component- and system-level will accelerate the design-in process and unlock the full Wolfspeed advantage.
