CAR AN-HV is used to simulate various types of transients that appear on the high voltage supply lines generated by the switching of various devices.
Pulse A represents ringing caused by switching operations of high voltage semiconductors. Pulse B represents sinusoidal waves generated by harmonics from the grid and revolutions from, for example, electric propulsion motors.
The CAR coupling network 50-1 is used to couple, according to ISO 7637-4:2020, the required sinusoidal disturbances into the DUT. This transformer also facilitates d.c. isolation of the LF generator from the DUT. The transformer has a current rating of 50A (rms) for the DUT.
