Abstract
A circuit arrangement having the function of preventing over-voltage damage which is structured by special copper foil or conductive wires and applies the burst absorption principle to form a short circuit from the input end and the output end of a circuit when the circuit is subject to an over-voltage or a transient electrical strike, so as to protect the electronic elements within the area of the circuit. The method can be put into application in a transformer, a switching power supply, an electronic computer, a solid-state relay and other similar electronic equipment. The arrangement of the present invention has undergone a number of high voltage and electrical striking tests with more than satisfactory results and is suitable for use in industries.
