Analysis of Transient Overvoltage Protection Circuits

Abstract

This report reviews the work performed during a research contract to a study was made of terminal protection devices (TPDs) for protecting electronic systems from damage by transient overvoltages. Analytical mathematical relations are given for standard surge test waveforms and the output of commercial surge generators are compared with these equations. Low-pass filters for use on the ac supply mains are evaluated as TPDs. A TPD for a system with a wide signal bandwidth (dc to 200 MHz) is discussed. Computation of energy in a surge from measurements of voltage alone across an unknown load is shown to be invalid. Nonlinear series devices are considered briefly.
