Abstract

The electrical equivalent circuits of electric-magnetic interfaces, inductors, and transformers are introduced. The analysis and design of integrated magnetics using these electrical equivalent circuits is described. The uneven flux density problem of integrated magnetics is studied. A possible solution to the problem is proposed. A boost-flyback SSIPP (single-stage isolated power-factor-corrected power supply) with regenerative clamping is used as an example to verify the application and performance of integrated magnetics
