Application of Filters for High-Altitude Electromagnetic Pulse Protection
Abstract
The application of filters for the protection of electrical equipment from electrical transient signals induced by high-altitude electromagnetic pulse (HEMP) is discussed, and the application of filters to ac and dc power supplies and analog and digital signal inputs is described. The application of filters is demonstrated for different types of filters; also shown are filter limitations caused by arching, source and load impedance mismatches, saturation, and parasitic reactances. The use of filters following a nonlinear terminal protection device (TPD) is shown to be a very effective means of transient energy reduction. Magnetic cores and ferrite beads can provide a simple method of high-frequency transient suppression.
