DanCap is currently a technology commercialization project.
Company formation is planned for Q1 2027.

Project DanCap

Today’s power-electronic systems demand components that are smaller, lighter, more efficient, and capable of operating at increasingly high switching frequencies. The DanCap project is developing a new high-voltage aluminum-polymer capacitor technology aimed at addressing these challenges.

From Research to Commercialization

DanCap is currently a technology commercialization project focused on bringing a new generation of high-voltage aluminum-polymer capacitors from research into industrial applications.
The technology originates from research and development within power electronics and capacitor technology and is currently undergoing further prototype development, validation and industrialization.
The objective is to establish DanCap as an independent company in Q1 2027, followed by the continued development and commercialization of the technology together with industrial partners.

Why DanCap?

Power electronics are becoming smaller, faster and more power-dense. Capacitors increasingly become a limiting component.

Combining advantages that traditionally require a compromise.
