Today, every single kilowatt of electricity powering our homes, industries, and transport passes through high-power magnetic components (HPMCs). From wind turbines to electric vehicles, these components are the silent workhorses of the green transition, and the need is bigger than ever. Yet their design and manufacturing have remained largely unchanged for a century, hampering innovations in renewables, electric mobility, and the broader green transition. 

Conventional foil-based magnetics are bulky, resource-intensive, and with limited use of recycling processes for small- and mid-scale components that rely heavily on non-ferrous metals and rare earth materials. These kinds of components typically achieve around 97% efficiency, meaning 3% of all generated electricity is wasted every second. Multiplying this by the world’s electrification needs, and the losses become staggering.

Adding to the challenge, HPMCs are typically produced outside Europe, exposing supply chains to volatility and geopolitical risks. These legacy constraints are hindering the speed and cost-efficiency of green energy deployment across Europe.

InnoMag steps into this gap, aiming to deliver planar magnetic components that are 50% smaller, 25% cheaper, and 40% more efficient, while using 30% less raw material and energy.

PIONEERING A NEW ERA

Planar technology, based on printed copper boards, has transformed electronics through time but its application to high-power magnetic components has long been deemed unfeasible. InnoMag confronts this challenge head-on by developing and prototyping the world’s first megawatt-level planar magnetic components. These will be rigorously tested in real electrification systems and benchmarked against the latest state-of-the-art solutions. 

The benefits will be threefold: greater sustainability, dramatically reduced production costs, and improved performance. By facilitating EU-based production, InnoMag also enhances strategic independence and supply chain resilience—critical in today’s geopolitically sensitive environment.

REIMAGINING HPMC WITH PLANAR INNOVATION

Today, there are three main approaches to manufacturing magnetic components: cable-based, foil-based, and planar-based technologies. At high power levels (>100 kW), foil-based magnetic components dominate the market. They are widely used, with more than 5,000 suppliers globally, and offer advantages such as mature production methods, high current capacity, and efficient cooling through integrated water-cooled panels.

Yet foil-based technologies face significant limitations; high manufacturing costs due to custom fixtures and poor performance at medium and high frequencies. Thus, there’s a need for a new type of components to enter the market of HPMCs – the planar-based technologies.

Enabled by three filed patents and more in the pipeline, InnoMag is setting a new standard for HPMCs. Based on groundbreaking innovations on the coil pattern and structures, and manufacturing technologies using the most standard and cheap PCBs (printed circuit boards), the technology has already proved successful in unlocking high-power applications at 50kW power levels (10x than conventional), while keeping a low cost and ultra-fast manufacturing. 

Its technology fundamentally redesigns how HPMCs are built, and compared to state-of-the-art solutions, InnoMag’s components can deliver:

• 50% smaller footprint and 25% lower cost
• 60% faster manufacturing cycles
• 30% less use of raw and rare-earth materials, with 30% less energy consumed in production
• 40% reduction in operational losses, improving energy efficiency at scale
• Full recyclability and reusability, advancing the circular economy

BACKED WITH MORE THAN DKK 50 MIO

Backed by numerous successful funding applications of more than DKK 50 mio combined, InnoMag and the groundbreaking technology has gained traction over the years. From AAU Proof of Concept to Otto Mønsteds Fond, a Villum Experiment grant, an Innoexplorer grant, Spinouts Denmark grant, and in 2025 a Grand Solution project supported by Innovation Fund Denmark, the potential of the technology is profound.
