Transformer with active elements

An active transformer of the type which includes two primary terminals to which is applied a voltage v.sub.1 with a current i.sub.1, and two secondary terminals supplying a voltage v.sub.2 with a current i.sub.2, when connected to a load current, said transformer comprising:

• a first circuit whose input, connected to said primary terminals, generates therein a current i.sub.1 ' = jC.sub.1 .omega.v.sub.1 and supplies a voltage f(v.sub.1) = jR.sub.1 C.sub.1 .omega.v.sub.1 ;
• A second circuit which converts said voltage f(v.sub.1) to a current i.sub.2 " = -jN.omega.v.sub.1 and which supplies said current i.sub.2 " at said secondary terminals of the transformer;
• a third circuit whose input, connected to said secondary terminals, generates therein a current i.sub.2 ' = jC.sub.2 .omega.v.sub.2 and supplies a voltage f(v.sub.2) = -jR.sub.2 C.sub.2 .omega.v.sub.2 ;
• a fourth circuit which converts said voltage f(v.sub.2) to a current i.sub.1 " = -jN.omega.v.sub.2 and which supplies said current i.sub.1 " at said primary terminals of the transformer;
• the terms C.sub.1, C.sub.2 and N being respectively the dual equivalents of the terms L.sub.1, L.sub.2 and M found in relations associated with a conventional transformer, and said currents satisfying the relations i.sub.1 = i.sub.1 ' - i.sub.1 " and i.sub.2 = i.sub.2 ' - i.sub.2 ".
