APPARATUS AND METHOD FOR TESTING RIPPLE CURRENT OF VEHICLE INVERTER CAPACITOR

摘要

The present invention relates to an apparatus for testing the ripple current of a capacitor for a vehicle inverter. The apparatus includes: a transformer (10) to convert AC power supplied from an AC power source into DC power; a voltage control converter (2) to set and output voltage of the DC power converted from the transformer (10); a current control converter (30) to set and output a ripple current value, a switching frequency, and a current waveform of DC power outputted from the voltage control converter (2); and a test target capacitor (40) electrically connected to the current control converter (30) to charge or discharge the current set and outputted from the current control converter (30).
