A Magnetic Amplifier Control Unit for Constant Frequency

Abstract

An line with a program for improving underwater log systems, a development problem for an improved constant-frequency control system was authorized. A control unit, in the form of a magnetic servo-amplifier and two resonant frequency-sensing circuits controlling the frequency of a rotary inverter, is described as solution to the problem.
