Build your power electronics setup, from the power stage to measurement, control and programming.
Power electronics · Designed, built and supported in Barcelona
We design and manufacture power converters — and, above all, the control that runs them — so every asset you connect to the grid delivers its full economic value. Open to its owner, with no dependency on third-party vendors, licences or remote services.
We contribute to progress and the energy transition with solutions for industry, institutions and individuals, from kWh to GWh: the same engineering problem, seen from two distances. And we help others contribute too, by designing equipment and building blocks for public and private R&D centres.
Power hardware, control firmware and software designed together, not integrated after the fact.
Documented interfaces and a control layer you can program, verify and evolve. Safety limits stay protected below it.
Design, manufacturing, testing and after-sales, all from Barcelona. 80% of our components are sourced in the EU.
Different approaches, using the same technological stack
EV charging at the lowest total cost, scalable without re-engineering.

B:SM, Barcelona’s municipal services company, selected our charging point through the InnovAcció 2030 innovation tender, aimed at lowering the cost of deploying EV charging.
Public EV charging · Municipal car parks · Barcelona
Before: adding charging points meant adding infrastructure, cabling and per-point costs.
After: a charging network that grows point by point, at a lower deployment cost. Wallare Park is protected by a European patent.
Partner in AGISTIN, an EU-funded project on advanced grid interfaces, alongside RTE, Shell, ETH Zürich, Fraunhofer and EPRI Europe. The project turns an irrigation canal into a flexible energy asset.
Irrigation canal · Water & agriculture · Maials, Lleida
Before: a canal, reservoirs at different heights and a solar pumping station, operated only to move water for irrigation.
After: the same infrastructure works as a flexible energy asset. Pumping and storage between reservoirs follow solar production and grid needs, through an advanced grid interface.
Estabanell Energia, a Catalan distribution system operator, deployed our Intelligent Distribution Power Router (IDPR) to dispatch power, filter it and back up supply at grid level.
Electric utility · Catalonia
Before: dispatching power, correcting power quality and backing up supply at the edge of the distribution grid usually requires separate equipment.
After: one modular cabinet, the IDPR, does all three: fully controllable three-phase dispatch, active filtering and battery-backed microgrid operation, configurable and operable remotely by the utility.
A high-current generator for testing power-cable connectors to IEC 61238: up to 26 kA of digitally controlled current, built from modular power electronics and energy storage, drawing just 20 kW from the grid.
Teknocea was founded in 2012 as a spin-off of CITCEA-UPC, the Universitat Politècnica de Catalunya’s research centre for static converters and drives. We understand our converters down to the control loop because we designed them there.
European design, firmware, manufacturing, testing and after-sales: European by design, not by assembly. That is what lets us open the system to its owner while keeping it closed to everyone else, and what makes it ready for programmes that require a European value chain.
