Abstract :
This paper describes a new coupling circuit applicable to both half-wave and full-wave magnetic amplifiers, particularly those amplifiers simultaneously requiring fast time response and large power gains. The pulse stretch technique uses a pulsating bias signal derived from an external supply to block the power winding of the reactor during reset. This blocking action permits free core control yielding an amplifier with an improved figure of merit.
