Abstract

A fail-safe logic circuit must switch the output signal to the logical value “0” when the operation circuit fails. Transformer has such favorable characteristics for fail-safe logic circuits that only the magnetic flux change is transmitted and that a superposition of magnetic flux is realized. So we applied those characteristics to a fail-safe logic operator. A new fail-safe logic operator using an insulated planar transformer was developed for a fail-safe majority operation and a fail-safe interlocking. In this paper, the principle, structure, fabrication and fundamental characteristics of the new fail-safe logic operator are described.
