Presentation

EMC tests on electric drive systems; technical and economic aspects

Electric drives in automotive technology currently require an operating voltage of up to 1000V. Higher EMC disturbances are to be expected, compared to 12V of conventional automotive electrics and electronics. Interferences on the motor shaft and coupling between the high and low voltage range are important new phenomena. Disturbances couple into the driveshafts and receiving antennas. Due to the high complexity of the motor, inverter and gearbox, the testing effort increases. Mooser's eCHAMBER is able to test these components together and reduce the costs for test bench times, personnel and measurement tasks by 95%.
