Abstract

To study the immunity of power chips to conducted electromagnetic interference, an electromagnetic pulse generator is designed based on the IEC 61000-4 series standards. First, mathematical models and their equivalent circuit models are proposed for the electromagnetic interference pulses in the existing standards, and the conversion relationship between the two is given. Then, based on the equivalent circuit model and relay switch, an electromagnetic interference generation module is fabricated and equipped with a main control module, high-voltage DC module, and display module to form an integrated testing device. Finally, the designed electromagnetic pulse generator is validated in the time domain. The results indicate that the output waveform of the designed electromagnetic pulse generator has high accuracy and can provide various pulse characteristic test waveforms for power chips.
