Power electronics laboratory

Product certification tests in accordance with UNE, EN, IEC and UL standards on power converters (AC-DC), to ensure their reliability and safety.

Our tests focus on the most critical part of conventional and renewable energy systems: solar power plants, fuel cells, storage systems, wind power plants, electric vehicle charging systems.
