Abstract: The invention relates to a transductor regulator with a magnetic core which is made up of a nanocrystalline alloy which is almost free of magnetorestriction. The core has as low cyclic magnetization losses as possible and as rectangular a hysterisis cycle as possible. Said alloy has the composition: FeaCobCucM?dSixByM?z, M? representing an element from the group V, Nb, Ta, Ti, Mo, W, Zr, Hf or a combination of these and M? representing an element from the group C, P, Ge, As, Sb, In, O, N or a combination of these and the following conditions applying: a+b+c+d+x+y+z=100%, with a=100%?b?c?d?x?y?z, 0?b?15, 0.5?c?2, 0.1?d?6, 2?x?20, 2?y?18, 0?z?10 and x+y>18. The inventive transductor regulators are particularly advantageously used in motor vehicle voltage supplies, rail power supplies or in aircraft power supplies.

Abstract: A resonant circuit successively assumes charging and discharging conditions which form the primary circuit of a transformer in a power pack constructed according to the principle of a resonant converter, and a switch-over pulse is generated after each initiation of the charging condition and depending on the existancee of current and/or voltage values for resonance in the resonant circuit, and the switch-over pulse ends the charging condition by using a switching means and initiates the discharging condition so as to produce an improved resonant converter.
