The flyback period is 60% (12 µs), and the time averaged secondary current for 100W output will be 5A. We have chosen to make secondary conduction period 10 µs.

The “transformer” is now wound using a wire size for the 60 turns primary that will use less than 50% of the bobbin area to allow for insulation. The remaining space is used for the secondaries.

The transformer gets hot because the core is saturating, and the whole thing takes several amps of current. it’s a great heater, but a very inefficient high voltage generator.

This article is based on the planar transformer of Flyback converter, and proposes a magnetic core partitioning design method to address the problems of poor flexibility and low space utilization of ...

The flyback converter utilizes a transformer with both primary and secondary windings, storing energy in the transformer core during the "on" time and releasing it to the output during the "off ...

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, ...

The flyback converter utilizes a transformer with both primary and secondary windings, storing energy in the transformer core during the "on" time and releasing it to the output during the "off ...

[Grenadier] Had some spare wire, electrical tape, and a giant ferrite core laying about and decided to create a massive and pretty snappy looking disk shaped flyback transformer. Dubbed the Fryback… ...

This Design Idea shows a way to drive low-power electronic circuits using a single 1.5V cell. The design is based on a free-running oscillator that drives a flyback transformer to generate a ...

The optimised feature set makes it perfect for use with SiC, IGBT and GaN switching elements in various automotive, industrial, and energy storage applications. The series flyback transformer is ...
