An integrated inductor comprising a multi-winding inductor having a transformer winding (L) and a resonant inductor (L). Sections (I), () of the magnetic circuit of the transformer winding (L) are incorporated into magnetic circuits of at least two parts (LA), (LB) of a resonant inductor (L) so as to form common parts of magnetic circuit of the multi-winding inductor (L) and at least two-part (LA), (LB) resonant inductor (L), wherein the transformer winding (L) of the multi-winding inductor is wound around a column (II), which has at least one air gap (G) having a width adapted so that the magnetic induction produced by the at least two-part (LA), (LB) resonant inductor (L) does not exceed 25% of the magnetic induction produced by the transformer winding (L) of the multi winding inductor.

Integrated inductor and a method for reduction of losses in an integrated inductor

Subject of the invention is a multi-resonance power supply with integral quality factor limiter, designated for transformation of direct voltages, characterised by high immunity to overload and rapid load changes. The power supply has the (TS) isolating transformer, with its primary winding connected to the main (OR) resonant circuit having at least one node connected with the set of (K), (K) current switches, via the serial resonant circuit, whereby at least one component of the serial resonant circuit is connected to the (DON) diode voltage limiter.
