Integrated magnetic component in a 2kW resonant power supply

The paper presents a design of a 2kW Resonant Power Supply dedicated for telecom applications. The power supply is based on a series-parallel LCLC resonant converter, which has some interesting features, such as self protection from load short-circuit. The design comprises an integrated magnetic component intended to be used as the resonant tank inductors. The construction presented in the paper allows for reduction of the size of the inductors and improves the magnetic core utilization. The paper explains the principle of operation of the integrated magnetic component, followed by functional and magnetic field simulations. Measurement results are presented for final verification.
