We're at the Fusion Industry Association's first-ever Fusion Supply Chain Trade Show in New Mexico.

And today, FIA released its 2026 report. Here's the headline: The industry is scaling fast. Supply chain spending rose 24% in 2025 and is projected to climb another 27% this year, to $681 million, with 75% of suppliers already investing to expand capacity.

The report also pinpoints where the strain is greatest. Power systems and components top the list of current bottlenecks, flagged by nearly half of fusion companies.

That's where we come in. Fusion requires two different power challenges to be solved. HDC capacitor film delivers the rapid, high-energy discharge needed for laser fusion and pulsed-power applications, while LDF film is designed for the high-voltage, high-temperature environments found in magnetic confinement fusion and next-generation energy infrastructure.

As FIA CEO Andrew Holland framed it, the race to fusion won't be won by whoever gets there first, but by whoever builds the strongest, most integrated supply chain. We agree, and we're building our part of it right here at home.

Stop by our booth to talk pulsed power and next-generation with our team.

Faster charging, longer range, healthier batteries. The move to and Silicon Carbide (SiC) promises all three... but only if the can take the heat and ripple.

In Wednesday's webinar with CHARGED Electric Vehicles Magazine, Shaun Walsh and Pam Wilson walked through the market dynamics.

First, 800V is going mainstream. New EV sales are climbing from about 2% in 2022 toward 40% by 2030, with buses, heavy trucks, and fast-charging infrastructure leading the way. And the payoff is already showing up: moving from 400V to 800V cuts charge time in half.

But there's a catch: none of it works unless the DC-link dielectric keeps up. Traditional film derates above 85°C, forcing designers to oversize, add cooling, and lose the very efficiency they were chasing.

On top of that, supply risk is compounding across resins, films, , and inverters, making domestic sourcing as important as performance and price.

So we built the fix. LDF is a low-loss, high-temperature nanolayered dielectric that holds its performance to 135°C and beyond and enables 25% higher current handling without derating. Paired with Advanced Conversion's Power Ring platform, it delivers a DC link purpose-built for 800V+ SiC on a fully domestic, allied supply chain. And it's ready for evaluation with Advanced Conversion's new HP Drive Test Kit.

We're at Penn State's Innovation & Emerging Plastics Technologies Conference in Erie, PA!

Senior Research Engineer Jessica Patz presented on how multilayer architecture (not new chemistry) is redefining what polymer films can do... from barrier performance to energy density and beyond.

This conference brought the industry together at Penn State Behrend campus' 10,500-square-foot processing lab, the largest and most comprehensive plastics training facility in the country.

Engineers designing 800V+ inverters have battled the limits of single-polymer films like BOPP for years. SiC runs much hotter, with faster switching frequencies and greater voltage endurance. But BOPP derates above 85°C, forcing workarounds to avoid failure:
❌ Derate the capacitor
❌ Oversize the assembly
❌ Add cooling infrastructure
❌ Accept packaging constraints

Advanced Conversion has built Peak's LDF capacitor film into its new HP Drive Test Kit, a high-voltage inverter solution for that engineers can evaluate now. It pairs NanoPlex LDF with Advanced Conversion's patented Power Ring integration platform, and it's the first product from our partnership... with more to come.

This combined DC-link solution was built for the demands of 800V+ SiC:
✅ No derating up to 135°C
✅ Sub-5nH commutation loop inductance
✅ Fully domestic, allied supply chain
✅ Full SiC performance

This turns a forced compromise for designers into a choice. They can either have a smaller, lighter capacitor, or achieve a higher voltage rating with the same amount of materials.

The DC-link capacitor has been the weakest link in SiC inverters. Not anymore.

Advanced Conversion has selected Peak's NanoPlex LDF film as the dielectric for its new HP Drive Test Kit, an 800V+ SiC inverter solution... and one of the first built entirely on a U.S. and allied-nation supply chain.

Here's the problem it solves. Silicon Carbide (SiC) switches fast, runs hot, and operates at high voltages. Conventional dielectric film can't handle the pressure. To cope, designers derate the capacitor, oversize the assembly, and add cooling. This eliminates the efficiency wins promised.

LDF removes that constraint:
🔹Holds 95% of room-temperature breakdown strength at 135°C
🔹Handles 25% more current than traditional film without derating
🔹Opens a 50°C margin so capacitors can sit right beside hot SiC modules

Designers can now use less film for a smaller, lighter, lower-cost capacitor... or capture a higher voltage rating in the same footprint.

Paired with Advanced Conversion's patented Power Ring platform, NanoPlex LDF is now shipping in a kit that engineers can evaluate against their inverter module of choice. It's the first product from our partnership, with more to come.

This is what we set out to build: a high-performance dielectric that would enhance on land, at sea, and in the air.

The polymers for next-generation high-performance film already exist. They're qualified and commercially available. Engineers have been working with them for decades across demanding applications.

The question engineers have historically asked is: How do I blend or layer my way to the spec, and do I need a new resin to get there?

The question worth asking instead: What happens when these same polymers are combined at the nanoscale?

Below about 250 nanometers, polymer behavior fundamentally changes. That's where operates. Conventional crystal structures are physically suppressed. New interfacial properties emerge. Performance that no single material could deliver (and that blending and bonding can't reach) becomes available through architecture alone.

There are 11 polymer families and 60+ standard polymers used across the medical, packaging, industrial, and electronics markets. These are the building blocks Peak Nano works with every day. Nanolayer coextrusion unlocks what none of them can do on their own.

The polymers aren't new. What we do with them is.

Your 800V+ SiC inverter is only as reliable as the DC-link film inside it.

DC-link capacitors have made do with high-temperature PEN HV film, but the leading supplier is exiting the market, creating a serious sourcing problem for EV inverter systems.

In our webinar next week with CHARGED Electric Vehicles Magazine, we'll share how Peak Nano's LDF film fills that gap. Our high-temperature dielectric is built to take the heat, voltage, and dV/dt switching throws at it. It drops into existing systems without redesign... and it's made in the U.S.

We'll cover:
– What 800V+ SiC applications require from a dielectric
– Where NanoPlex LDF lands against those requirements
– How NanoPlex fits into Advanced Conversion's Power Ring platform
– Why multi-year inverter programs need a domestic film supply
– Open technical questions and our testing roadmap

has had a big week. Five top U.S. fusion companies have made headlines:
🔹 Helion closed a $465M Series G at a $15.5B valuation, bringing its total raised to roughly $1.5B. Its pulsed magneto-inertial machine, Polaris, recently became the first privately developed system to run on deuterium-tritium fuel and topped 150 million °C.
🔹 Commonwealth Fusion Systems published five peer-reviewed papers further validating the physics of ARC, the tokamak power plant it expects to deliver 400 MW of net electricity to the grid in the early 2030s.
🔹 Pacific Fusion hit its second technical milestone on the path to affordable inertial fusion, validating a scaled prototype of its pulser module and clocking more than 440 gigawatts of peak power in an 80-nanosecond burst.
🔹 Thea Energy is building the first digital twin of a stellarator power plant. It's working with NVIDIA, Synopsys, and the DOE's Argonne and Princeton Plasma Physics labs to use AI to speed up and stress-test its Helios design.
🔹 Xcimer Energy switched on Phoenix, which it says is the largest privately owned laser in the world. This is a step toward the laser-driven inertial fusion plant it aims to prototype by 2028.

AI data centers are driving power demand to unprecedented levels, the first fusion power deals are already signed, and capital is following fast. Behind it sits a real contest with China, which has poured billions into its state-backed fusion program. Global energy leadership is on the line.

Fusion machines share one job: Store an enormous amount of energy, then release it in a precisely timed burst. Whether that energy drives magnets, lasers, or a direct electrical pulse, it runs through capacitors first.

Sandia's Randy Curry has said fusion machines will need "warehouses of capacitors." The hard part? Scale. Even China, for all its spending, has hit supply-chain choke points and has been forced to lean on foreign-made components.

run on dielectric film, and today, most of that film comes from overseas. If the U.S. is going to lead fusion, the materials that underpin these plants can't sit offshore.

That's the gap we build for. Our capacitor film is 100% U.S.-engineered, backed by an allied nation supply chain, and designed at the nanoscale for duty.

The EV industry's push to higher-voltage battery architectures and wide-bandgap semiconductors like silicon carbide (SiC) has elevated the demands of traction inverters and drivetrain power systems, where capacitors are critical. Conventional can't keep up with new efficiency, thermal management, and power density requirements, and it's directly impacting EV energy efficiency and system reliability.

Everything PE covered how LDF capacitor film closes this gap: lower dissipation factor to reduce internal heat generation, stable performance under the high switching frequencies of inverters, and long-term reliability under high voltage, elevated temperatures, and continuous power cycling.

The result: smaller, lighter, more efficient drivetrain systems... optimizing system performance and increasing driving range.
