About

The Mooser group runs two DAkkS-accredited EMC laboratories - Jakob Mooser GmbH at Egling-Thanning south of Munich and Mooser EMC Technik GmbH at Ludwigsburg near Stuttgart - and has specialised for more than thirty years in the electromagnetic behaviour of high-voltage automotive drive systems. Its defining asset is the eCHAMBER test bench, of which the group operates four: purpose-built enclosures that let a traction inverter, electric machine, DC/DC converter or complete high-voltage powertrain be run under realistic electrical and mechanical load inside a controlled EMC environment, which is what makes emission measurement on a switching drive at full power meaningful rather than notional. A reverberation chamber complements the absorber facilities for immunity and shielding work. Service lines follow the electrified drivetrain end to end: traction battery and fuel cell stack EMC measurement, power-semiconductor and module-level emission characterisation, high-voltage cable and connector work, AC and DC charging system testing, and shielding effectiveness measurement on housings, cables and enclosures. Both laboratories hold DAkkS accreditation to DIN EN ISO/IEC 17025 and the group is a designated Technical Service of the German Federal Motor Transport Authority (KBA) for UN-ECE R10 type approval. Alongside measurement, Mooser provides EMC consultancy and interference-suppression design, which is how most customers use it - as a development partner that both finds the emission and specifies the filter or shield that fixes it. Specialisations are electric mobility and high-voltage powertrains, power electronics and semiconductors, and military, railway and industrial equipment.
