Power amplification with gate turn-off controlled rectifiers

Abstract

With ever larger amounts of power being required by present day active sonars, studies are being made towards improving the efficiency of the power train. A gain in efficiency is possible if non-linear switching type amplifiers are used in lieu of the linear amplifiers presently used. Due to its high switching efficiency, fast switching, and ability to be turned on or off by gate signals, the Gate Turn-off Controlled Rectifier was investigation for possible application in an amplifier circuit. The circuit examined readily met the required criteria, however, the real value of this study lies in the method of predicting transient performance. Use of this derived equivalent circuit, and an analog computer model based on the transfer functions (E(L)/E and I(1)/E), provide analytical solutions that can be arrived at more readily than by other methods.
