A Magnetic Amplifier Control Unit for Constant Frequency

摘要

In 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 a solution to the problem.nAmong the circuit and component design considerations, those concerned with saturable reactors and anti-hunt or damping methods may have general applications to frequency controls and servo systems.
