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. Lumped geometrically scalable modelling of the most adopted isolation transformer topologies are presented and compared. Transformer models have been validated by means of electromagnetic simulations in a wide range of geometrical parameters, achieving absolute errors lower than 12% for inductance, Q-factor peak, self-resonance frequency, and magnetic coupling factor.

Abstract
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. Lumped geometrically scalable modelling of the most adopted isolation transformer topologies are presented and compared. Transformer models have been validated by means of electromagnetic simulations in a wide range of geometrical parameters, achieving absolute errors lower than 12% for inductance, Q-factor peak, self-resonance frequency, and magnetic coupling factor.File | Dimensione | Formato | |
