Magnetic regulator modeling

A method of providing regulation in a resonant power supply uses a device called a magnetic regulator which resembles an ordinary AC transformer. Through the use of additional control windings, the conversion ratio of the magnetic regulator can be electronically varied, thus achieving control. A circuit model for the magnetic regulator is derived and is shown to contain a current-controlled leakage inductance. Measurements made on an experimental device verify the model. Two additional structures are described.
