This work presents a review of integrated transformers for galvanic isolation with particular focus on their modelling in power transfer systems. A comparison between transformer-coupled oscillator topologies is carried out, highlighting the main differences in the realization of the isolation transformers. A novel lumped geometrically scalable model of three-windings transformer for current-reuse hybrid-coupled oscillators has been developed and compared with previously reported models. This transformer has been validated by means of electromagnetic simulations in a wide range of geometrical parameters, achieving an absolute error lower than 8% for inductance, Q-factor peak, self-resonance frequency, and magnetic coupling factor.
