Abstract:
     The making of the core is characterized by using the special cold working process and the special final heat treatment so that the core has a wide range of usable magnetic field from O to 8 Oe, a high permeability up to 1000 Gs/Oe in a superposition of Ac magnetic field and Dc magnetic field and a high inductance. The core loss is so low that it can be utilized in a frequency range from 1 K to 20 KHz. This core can be used for inductor in a DC power supply, energy storage element in a HF power supply, isolating transformer and pulsing transformer in a pulsing power supply.
