Application9 Magnetic Field Analysis of Magnetic Transformer

Magnetic flux distribution of an integrated magnetic transformer for the switched-mode power supply was analyzed.
The switched-mode power supply is controlled by on/off of the semiconductor switch, and the transformer functions as a component of nonlinear circuit.
The behavior of the magnetic fields was calculated for each time segment.
Femtet® contributes to the development of the highly efficient switched-mode power supply and its miniaturization.
