Electronic Alternating-Current Power Regulator

The object of this paper is to describe an electronic alternating-current power regulator, which is instantaneous and independent of frequency. The theory and design considerations governing a conventional circuit using gaseous discharge tubes are presented. The effect of the extent of voltage-limiting by the gas tubes on the degree of regulation is discussed. A bridge-type circuit is described and its theory developed. The effect of the degree of unbalance of the bridge circuit on the degree of regulation is discussed. The application of these circuits for regulation of low power, particularly the use in electronic apparatus, is treated and performance data on both circuits are given.
