Abstract
An electromagnetic flux suppression includes a three stage filtering system to protect against electromagnetic interference and electrostatic discharge and has a first stage high voltage section that filters a high voltage pulse by providing a spark gap to ionize the ambient air and thus effectively form a shunt. A second stage filter has a front end capacitive interface followed by an inductive line to filter out radio frequency arcing that occurs between two bodies thus exposing them to radio frequency radiation. A third stage filter includes a radio frequency low pass filter to reinforce the capacitive inductance filter.
