HIGH TEMPERATURE SUPERCONDUCTING CONTROLLED RECTIFIER

摘要

This invention relates to a new class of superconducting current control devices which possess voltage-current relationships similar to those of semiconducting diodes and controlled rectifiers. This is achieved by the application of weak magnetic fields to a polycrystalline high temperature superconducting element. A variety of connection schemes are possible which allow two terminal devices with assymmetric voltage-current relationships (diodes) and various three and four terminal devices with properties similar to semiconducting controlled rectifiers.
