When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...
The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...
Designing flyback transformers for switch-mode power supplies involves many calculations. A spreadsheet can make short work of this otherwise-tedious task. When you develop flyback power supplies, ...
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 ...
