Designing a Discontinuous-Conduction-Mode Flyback Transformer

Flyback transformers come in two flavors: CCM (continuous conduction mode) and DCM (discontinuous conduction mode). The DCM version is the one we will develop here. The idea of the DCM flyback is that ...

Modes Of Conduction

Various power-converter architectures use their transformer in different modes. In continuous conduction mode (CCM), the magnetic field never completely collapses due to the transformer's mode of ...
