Test system for automotive applications

for electrical networkshigh-voltagelow-voltage

Testing of power converters for automotive applications increasingly includes testing under low temperatures from -40°C to high temperatures of about 110°C. The realised test consists of a run-in run with high phase currents at the different temperatures. In addition to the circulating air temperature control, a cooling liquid temperature control is also implemented. The test stand can test 2 DUTs simultaneously and can be switched between high-voltage and low-voltage (48V) applications. The test item-specific part fixtures are interchangeable. The temperature cycle test is usually carried out during series production.
