Innovative 2300V modules utilize 200mm silicon carbide technology to deliver energy efficiency for various applications, including renewable energy, energy storage, and high-capacity fast-charging infrastructure

Company announces partnership with EPC Power, a premier utility-scale inverter manufacturer

Wolfspeed, Inc. (NYSE: WOLF), the global leader in silicon carbide technology, today unveiled a silicon carbide module designed to transform the renewable energy, energy storage, and high-capacity fast-charging sectors through improved efficiency, durability, reliability, and scalability. The 2300V baseplate-less silicon carbide power modules for 1500V DC Bus applications were developed and launched utilizing Wolfspeed’s state-of-the-art 200mm silicon carbide wafers.

Wolfspeed also announced today that it is partnering with EPC Power, a premier North American utility-scale inverter manufacturer. EPC Power will be employing the Wolfspeed® modules in utility-grade solar and energy storage systems, which offer a scalable high-power conversion system and high-performance controls and system redundancy.

“The solar and energy storage market remains among the fastest-growing segments of the renewable energy industry. As the pioneers of silicon carbide, we are driven to create solutions that will open the door to a new era of modern energy,” said Jay Cameron, Wolfspeed Senior Vice President and General Manager, Power. “Energy efficiency, reliability, and scalability are top of mind for our customers, such as EPC Power, who recognize the substantial advantages Wolfspeed’s silicon carbide brings to the table.”

“Silicon carbide devices open the door to a step-change in inverter performance and reliability. With our commitment to extreme reliability, performance, and security in our new ‘M’ inverter while also forging a deep commercial relationship with key suppliers, Wolfspeed was the obvious choice,” said Devin Dilley, President and Chief Product Officer, EPC Power.

With mounting global investment in renewable energy, the solar energy market is estimated to reach a $300 billion market capitalization by 2032.[1] According to the International Energy Agency (IEA), 2024-25 will see the highest energy demand growth rate since 2007, reinforcing the need for efficient and reliable clean power.[2] Wolfspeed’s silicon carbide solution helps bridge this crucial gap, supporting the next era of modern energy technologies while reinforcing U.S. clean energy manufacturing leadership.

Cameron continued, “This platform further validates our investments in 200mm wafer technology and production as the potential of silicon carbide continues to be recognized by industry leaders across all mission-critical applications.”

Industry Leading Switching Performance

Wolfspeed’s 2300V modules will improve system efficiency, while reducing the number of passive components. They offer 15% greater voltage headroom compared to similar silicon carbide modules, improved dynamic performance with consistent temperature stability, and a substantial reduction in EMI filter size. Wolfspeed’s technology achieves a 77% reduction in switching losses over IGBTs and a 2-3x reduction in switching losses for silicon carbide devices intended for 1500V applications.

Market Scalability Through Design Simplification

2300V silicon carbide modules will allow system designers to leverage lower cost printed circuit boards to cut manufacturing costs and significantly reduce development time compared to legacy bus bar solutions.Furthermore, Wolfspeed’s 2300V modules will enable the industry to adopt the two-level topology, resulting in simplified system design and reduced driver count compared to IGBT-based three-level configurations. The benefits of 2300V modules support a building block approach to easily scale power tenfold, from kilowatts to megawatts.

Prolonged System Lifetimes & Durability

Wolfspeed’s 2300V silicon carbide modules will allow customers to further enhance the lifetime and durability of their systems. This is achieved through an optimized Failure in Time rate for continuous 1500V DC operation and improved cosmic ray susceptibility compared to a 2000V design. When used in a two-level implementation, 2300V modules reduce the amount of potential single points of failure across the system.

For decades the power grid has served as a reliable conduit for electricity between power producers and consumers, seamlessly delivering electricity with the flip of a switch. Increasing demand for electricity created from renewable sources, including solar and wind, creates new challenges for the existing power grid including integrating energy storage to ensure sufficient electricity during peak use times.

EPC Power, a premier utility-scale inverter manufacturer offering cutting edge power conversion solutions, has partnered with Wolfspeed to create a solution to the energy storage challenge. Utilizing the power of silicon carbide, “M” is the industry’s first utility-scale string-style inverter that makes grid-tied energy storage more efficient, reliable, and scalable than ever before.

‘M’ is for Modularity

Traditional energy storage systems use central inverters in power conversion. These monolithic devices operate at 4-6 megawatts and are prone to downtime due to the system size and complexity. Central inverters are further taxed when storing significant loads of renewable energy for extended periods of time.  EPC’s “M” inverter combines the flexibility of string-style inverters typically seen in residential and commercial solar systems, with the scale necessary to power entire cities with renewable energy.

Using a modular approach “M” enables customized central-style inverters by connecting multiple small inverters. “M” inverters are significantly smaller with fewer passive components, have a wide AC and DC operating range and offer world-class power density. The “M” modular system is easier to install and maintain than central inverters and delivers superior up-time with fewer points of failure.

“M” bridges the gap between two inverter architectures creating stable and reliable battery storage at a significantly higher voltage level. By breaking energy into smaller blocks, power companies can design inverter systems to better match specific needs at specific energy storage sites.

The Key to Innovation

“Technology unlocks business opportunity. Silicon carbide is a tool and if you can glean the benefits from it in the system you can make a paradigm shift in technology. Wolfspeed SiC is enabling EPC to make a paradigm shift in how energy is created and stored globally.”

Devin Dilley
President & Chief Product Officer, EPC

EPC knew leveraging the unique benefits of silicon carbide was key to unlocking reliable energy storage at the grid-level. Wolfspeed’s new 2300 V silicon carbide Wolfspeed WolfPACK^TM power module was designed specifically for 1500 V bus applications and enabled the shift from a typical three-level architecture to a simplified 2-level power conversion system. This solution significantly cut development time and cost by moving the system design from a legacy bus bar to lower cost PCBs.

SiC module’s switching performance enabled EPC to dramatically scale down the size of “M,” reducing the number of passive components and overall system cost.  This innovation makes installation and maintenance easier creating the industry’s first inverter optimized for utility-scale battery energy storage.

EPC worked closely with Wolfspeed experts to prolong the “M” system’s lifetime by maximizing the 2.3 kV WolfPACK’s 7-8x reduction in cosmic ray FIT compared to a similar 2 kV device. Capitalizing on this feature enables M’s longer lifetime and higher reliability which directly translates to less field failures and lower maintenance costs.

The Power of Partnership

As the creator of the world’s most advanced silicon carbide semiconductor technology, Wolfspeed provides hands-on support throughout the design process to help customers maximize the benefits of silicon carbide. This philosophy guides Wolfspeed’s partnerships with innovators in the marketplace and enables the world’s most disruptive technologies.

“EPC and Wolfspeed’s philosophies align so well. How can you not partner with the company that pioneered the commercialization of silicon carbide and is years ahead of the competition?”

Adam Kabulski
Vice President, Global Sales & Marketing, EPC

“Wolfspeed and EPC came to the table, rolled up their sleeves and got to work,” said Jay Cameron, Vice President and General Manager for Wolfspeed Power. “I am impressed with EPC’s level of ambition and capability, pushing all of us to move efficiently toward the launch of products that revolutionize the grid and provide a more sustainable future for us all.”
