The integration of inductor (L), capacitor (C) and transformer (T) to one L-C-T element is one key technology for future power supplies. The four-pole configuration presented here is an extension of common cases like integrated series or parallel resonant circuits. It exhibits properties beyond simple series or parallel resonances like inverse impedance transformation, all path behaviour or resonance voltage doubling. The voltage and current distribution as well as current losses are calculated. They differ from the uniform voltage and current distribution in a discrete circuit.
