SAXOGY

What SAXOGY does

SAXOGY POWER ELECTRONICS GmbH is a privately held German engineering company founded in 2004 and headquartered in Chemnitz, Germany. The company designs, manufactures, tests, and maintains specialized safety measurement equipment and test benches for the power electronics industry, with a portfolio organized across four pillars: electronics development (including the High-Voltage Stress Generator for insulation testing and thyristor-controlled precharging systems), drivers for power semiconductors (single and multi-channel thyristor gate drivers and custom IGBT gate drivers developed over 18+ years), test benches and safety equipment (the SMP-III/SMP-V/SMP-III eco safety measurement stations certified to Performance Level PLe, plus the SMB safety measurement box, SMK modular safety cabin, SMR rack-mount system, and LSS-x laboratory safety control), and research/testing services (insulation endurance testing, breakage current analysis, and pulse-current-resistant contact development).

Underlying technology spans analog and digital circuit design, power electronics (SiC, GaN, IGBT, thyristor), adaptive circuit topologies engineered to avoid obsolescence from highly integrated component shortages, mechanics and fluid technology for high-current contacting, and control/safety engineering. Differentiated technical capabilities include bipolar voltage stress up to 12 kVpp with slopes to 200 kV/µs, inductive loads up to 2,000 A peak, presspack contacting forces up to 300 kN, and integrated safety architectures that achieve the highest machinery safety performance level (PLe).

The business model is direct B2B enterprise sales of custom-engineered solutions — pricing is quote-based with no public pricing or self-serve channels, and customers engage SAXOGY when no off-the-shelf solution exists. The company operates exclusively through its own technical sales force and engineering team, with worldwide delivery capability and a stated European/global geographic footprint. Customer base spans automotive and electromobility OEMs, semiconductor manufacturers (including Infineon Bipolar), energy sector buyers (Siemens Energy), electronics components firms (TDK), engineering services (Bertrandt, ZF), and academic/research institutions in Germany. SAXOGY has approximately 30+ employees, is owner-managed (CEO Konrad Domes), bootstrapped with no external institutional capital, and is a member of ECPE.
