Abstract :
RECENT papers have indicated a strong interest in the operation of magnetic amplifiers with carrier frequencies higher than the common power frequencies of 60 and 400 cycles.1,2 Much work has been carried out, e.g., on magnetic frequency multipliers that would be a possible source of power at higher frequencies.3,4 It is generally known that increased magnetic amplifier performance can be achieved by using higher carrier frequencies, but the exact advantages have not been clearly defined in the literature.
