Analytical model of a resonator for PCB-embedded power conversion

This study proposes a comprehensive analytical model of the magnetism, electrostatics, and loss mechanisms of a simple and economical structure with a printed circuit board-embedded magnetic component (coil, high leakage transformer, or resonator) for electric power conversion in the range 1 W–100 W...

Summary:This study proposes a comprehensive analytical model of the magnetism, electrostatics, and loss mechanisms of a simple and economical structure with a printed circuit board-embedded magnetic component (coil, high leakage transformer, or resonator) for electric power conversion in the range 1 W–100 W. The predictions of this model are compared to finite element simulations. A good match is obtained over a wide bandwidth (up to at least 10 MHz). The model is adapted to predict the electrical characteristics of the device used as a monolithic series-LC tank, with a resonant frequency in the MHz range. A prototype is built to prove the applicability of the model, which is intended for the design and optimisation of power electronics converters.
