Development of IEMI Generator for High Voltage EV Component EMC Test

Through Intentional Electromagnetic Interference (IEMI) generator design, a simulator was developed for the purpose of studying the effects of damage in the intentional EM disturbance environment test of unmanned aerial vehicles, ships, railroads, and electric vehicles & autonomous vehicles. The IEMI generator used Marx topology as a multi-stage pulse forming device. It was manufactured to make it compact, lightweight, and capable of control using SiC MOSFET devices instead of the spark gap, which is a mechanical component. Using IEMI generator, it is possible to secure countermeasure technologies such as electromagnetic wave robust design technology such as verifying conducted immunity of electric vehicles and future autonomous vehicle component and designing EMI filters.
