Patent abstract

A high temperature magnetic amplifier, which utilizes the nonlinear properties of square loop magnetic cores to achieve very large amounts of both voltage and power amplification. By combining square loop, grain-oriented magnetic materials with high temperatures along with high temperature packaging approaches, high temperature long lifetime components can be produced. The high temperature magnetic amplifier is used as a building block to develop high temperature versions of operational amplifiers, comparators, voltage regulators, timers, counters, modulators, motor starters, servo systems, converters, inverters, power switches and many other devices.
