Abstract

A series of circuits are presented which use a magnetic amplifier to control the average output power of switching transistors by pulse-width modulation. Thus the advantages of switched-transistor operation are incorporated in a linear amplifier. The magnetic elements serve both as a pulse-width modulator and as a high-gain preamplifier, thereby producing an amplifier with high-gain as well as high-output power. Design considerations, performance data, and potential applications of the circuitry are discussed.
