The 3-phase full-wave ramey-type magnetic amplifier is far superior to its single-phase counterpart in band-pass characteristics.1 In the single-phase unit, phase detection effects which produce beats in the output begin to occur with control frequencies of two-thirds of the carrier frequency. In a properly balanced 3-phase system, phase detection does not occur until the control signal frequency is raised above twice the carrier frequency.
