This paper reports the high frequency characteristics of Co-rich amorphous tape wound cores under the flux resetting characteristics up to 2O0kHz. The characteristics can be utilized for magnetic amplifiers in a switched-mode power supply. The advantages of the amorphous cores have been clarified as compared with 50%Ni-Fe, 79%Ni-Fe and Mn-Zn ferrite cores. Some problems related to the stability and...
