Magnetic-amplifier circuits with full-wave output and half-wave control signals

摘要

THE advantages of half-wave magnetic-amplifier circuits of the flux reset type have been described in several papers.1,2 However, when several such amplifiers are cascaded and the output is used to drive a servomotor, the output often is allowed to be a half-wave.3 This sort of output has proved satisfactory for either d-c motors or 2-phase a-c motors if a small derating of the motor output is accepted.
