Simulation of EMP generator using MATLAB

Abstract

Electromagnetic pulse (EMP) is a sudden burst of wide-band, high-intensity electromagnetic radiation. EMP also called as a transient electromagnetic disturbance, a short burst of electromagnetic energy. Effect of EMP to automobile is classify as medium threats to vehicle attacks where EMP aims at damaging electronic devices such as on board sensors and processors, CPU which found in almost all models from 1990’s and forward. This paper presents a MATLAB simulation of EMP generator by means of Switch Mode Power Supply, thus the electrical shielding can be studied further. Theoretically, EMP generator is developed by implementing energy storage circuit and discharge control circuit. Sending a rapidly changing electrical current through a loop will create an electromagnetic field in the form of a pulse. The results show an increase in pulse voltage from 12 VDC to 758 VDC with a current of 1500 A. A MATLAB model on the coverage area affected by EMP pulse will be developed in the next phase of the research.
