- 28 - Abstract of the Disclosure A high frequency switching circuit comprised of a single-ended switching circuit, rectifying-smoothing circuit and magnetic amplifier which is connected between said single-ended switching circuit and rectifying-smoothing circuit. The magnetic amplifier includes a saturable reactor which has a coercive force Hc of 0.6 Oe or below and a rectangular ratio Br/Bs of 80% or below at an operating frequency of 20 kHz. The saturable reactor is prepared from an amorphous magnetic alloy having a composition of (co1-a-b-c Fea Nib Mc)l-d Xd where: M = one element selected from a group consisting of the elements of Nb, Cr, Mo, V, Ta, Ti, Zr and W X = B or a compound of B and Si in which the content of Si is set at 25 atomic % or less 0.04 ? a ? 0.15 0 ? b ? 0.10 0.005 ? c ? 0.10 0.15 ? d ? 0.30
