Announcing the Wolfspeed WolfPACK™ Power Modules

Introducing the newest member of the power modules family, the Wolfspeed WolfPACK GM3.

For years, Wolfspeed has been the leader in Silicon Carbide (SiC) power products. In fact, Wolfspeed was the first to commercially release a Silicon Carbide MOSFET and is dedicated to designing Silicon Carbide components that help power today’s most innovative technology solutions.

Wolfspeed is excited to announce the company’s newest line of Wolfspeed WolfPACK power modules, which are specially designed to bridge the gap between single die discrete components and high-ampacity module solutions, giving today’s design engineers a true end-to-end solution for all system design needs using Wolfspeed Silicon Carbide.

Overview

Wolfspeed’s WolfPACK modules are all about choice and flexibility. In the past, design engineers had limited options for their medium-power applications. It often came down to choosing either a higher-current module that was overkill for the design or creating a system that used multiple discrete components arranged in series and parallel, leading to increased design complexity.

Wolfspeed WolfPACK changes all of that, and here’s how: For starters, the heart and soul of these new modules are Wolfspeed Silicon Carbide devices, which means it is built upon the same technology that has made Wolfspeed the world’s most trusted manufacturer of Silicon Carbide technology. With Wolfspeed WolfPACK, you get the same reliability and quality you’ve come to expect from Wolfspeed Silicon Carbide devices.

Wolfspeed WolfPACK modules make system design flexible, using press-fit pins to make both prototyping and manufacturing easy. Press-fit pins are far more reliable than both traditional hand soldering and automatic soldering.

For engineers working in the mid-power range, maximizing power density while minimizing design complexity is essential -- and those are two areas where the Wolfspeed WolfPACK modules shine. With the simplicity of this module design, engineers can enjoy the efficient, powerful performance of Wolfspeed Silicon Carbide (proven to provide increased ampacity and reliability), while keeping system layouts simple with straightforward design and assembly processes. Systems built around Wolfspeed WolfPACK lend themselves to scalability to help accelerate your production pipeline and help lower your system assembly costs. These new Wolfspeed WolfPACK modules come in all Silicon Carbide MOSFET half-bridge and all Silicon Carbide MOSFET six-pack configurations with a variety of milliohm options.

Features

• Versatile, Industry-Standard Housing with Multiple Configurations and Topologies
• Press-Fit Pins & Flexible Metal Spring Mounting to Speed Time to Market with Simple System Implementation
• Lower Weight & Decreased Footprint Compared to Traditional Modules with Baseplate & Screw Terminals
• Reduced Assembly Cost Compared With Automatic Soldering

Benefits

With the introduction of Wolfspeed WolfPACK modules, our power portfolio now covers the entire spectrum of applications, providing choice to designers in diverse applications — from single-kilowatt designs to megawatt systems. These modules offer tremendous performance and proven Silicon Carbide reliability based on their flexibility, scalability, and because they are built with the backbone of Wolfspeed’s industry-leading Silicon Carbide technology.

Wolfspeed WolfPACK modules are simple and designed to provide clean, reliable power for energy conversion systems. By leveraging years of industry experience, Wolfspeed has done the heavy lifting to ensure that these modules offer incredibly low losses in a package that lends itself extremely well to automation and manufacturing at scale. Wolfspeed WolfPACK power modules feature a compact footprint and can be used to design a streamlined, higher power density system. They can help system designers enable a more compact solution than achievable with either multiple discrete devices or with larger, high-ampacity modules.

Applications

The beauty of Wolfspeed WolfPACK modules is in their flexibility, which is why Wolfspeed WolfPACK is well-suited for a wide variety of applications, including:

• Electric vehicle fast charging
• Standard and uninterruptible power supplies
• Industrial power solutions
• Induction heating and welding
• Solar and renewable energy
• Grid infrastructure applications
• Industrial motor drives
