ABSTRACT:
A bulk current injection (BCI) system and method for testing electromagnetic susceptibility of electrical apparatus includes an RF modulator in a BCI setup. The BCI setup with RF modulator injects high instantaneous currents with a very low, controllable duty cycle into a wire under test, thereby simulating an electromagnetic environment to which electrical equipment is exposed during an electrical transient event. The RF modulator provides an amplitude modulated envelope for removing undesirable transients. Injecting currents at selectable frequency, one frequency at a time, allows for frequency-amplitude electromagnetic susceptibility mapping for each major wire within an electrical apparatus.
