In a conventional diode-rectified flyback converter, the output diode rectifier is a substantial power-loss contributor. The average current in the output diode is equal to the dc output current, and ...

The choice between a flyback or single-ended primary inductance converter (SEPIC) topology often ends with the designer choosing the most familiar one, but that’s not always the right option, say John ...

The flyback is a popular topology for low and medium power AC-DC converters, mainly because of its low cost and ease of use. The flyback assumes a DC input, and includes a transformer, a power switch ...

Rfb is shown in Figure 2. With it, the output voltage can be adjusted. Nps is the turns ratio of the transformer used, and Vf is the voltage drop across the secondary-side flyback diode. This is ...

The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance at little or ...

Linear Technology’s LT3809 flyback secondary-side synchronous rectifier driver replaces the output diode forward-voltage drop with the RDS (ON) of an external N-channel MOSFET, thus reducing the ...
