Technical analysis of planar transformer in switching power supply
The design of magnetic components is an important part of the switching power supply, because the planar transformer has a great advantage in improving the characteristics of the switching power supply, so it has been widely used in recent years. For an ideal transformer, the flux produced by the primary coil passes through the secondary coil, that is, no leakage flux. For ordinary transformers, the flux generated by the primary coil does not all pass through the secondary coil, thus causing leak…
