In order to carry out the lightning indirect effect test on ordnance, a kind of lightning current component A generator based on intelligent control is designed and developed. The generator uses constant current charging mode to charge the capacitors. Through the calculation and analysis of the discharge circuit, we get the parameters needed to generate the standard waveform of lightning current component A. The device is controlled by the intelligent control system. It is easy to operate and reliable. The test results show that the generator can produce standard waveform of lightning current component A with the peak of 0.6-17 k A. The output waveform meets the requirements. The generator provides equipment support for the subsequent research on the lightning indirect effect on ordnance.
