From inverter to OBC

Power electronics safely tested

In electrified drives, power electronics determine efficiency, safety and reliability. With high-precision measurement technology, flexible test environments and standard-compliant procedures, we safeguard your components - resilient, reproducible and ready for series production.

Reliability under high-voltage conditions

Electrical intelligence needs reliable data

Whether control, conversion or charging infrastructure - power electronics are the nervous system of electrified drives. PTS-Prüftechnik tests your systems under voltage, temperature and time pressure: with automated test benches, real-time analysis and standard-compliant documentation. So that your components are ready for use - and react precisely even under load.

Electronics that show performance

Our test benches simulate voltage fluctuations, EMC faults and load change cycles - reproducibly, automatically and documented.

Scope of services:

High-voltage, insulation and breakdown tests
EMC and HF immunity tests
Thermal characterization incl. heat sink evaluation
Endurance & load cycle tests
Validation of protective functions (overcurrent, overvoltage, etc.)
Software communication tests (CAN, LIN, Ethernet)

Secure your certification with reliable measurement data.
