Flyback circuit provides isolated power conversion - 01/07/99 Issue of EDN A common requirement in telecommunications systems is to convert an unregulated 48V line to an isolated, accurate dc supply voltage. The circuit in Figure 1 provides a 5V, 15W output. The circuit uses a UCC3809 primary-side controller, which can also control other single-ended converters. The topology uses peak-current-mode control with a fixed-frequency oscillator. The design is cost-efficient.....Page includes several designs. Scroll to find this one.....

Flyback Converters for Dummies - In the NIXIE clocks that I have built, I did not want to have the big and ugly mains transformer in the actual clock itself. Instead I use an AC adapter that fits into the mains wall plug. This means that I have to use some sort of an up-converter to generate the 180V anode supply for the NIXIEs.....(added 07/07/07)

Flyback LDO Buck Sync. Buck Reference Design - Flyback, LDO, Buck and Sync Buck with Vin 10 to 16 V. Multiple output voltages of -24 V, -5 V, 1.5 V, 3.3 V, 5 V, 12 V and 58 V. The total output power is 15 W. (added 3/05)

Flyback Transformer Driver - This is by far the best project for someone who is already familiar with High Voltage, but wants to take their experiments to the next level: It requires very little previous experience and skills with soldering and identifying components, and there are virtually no adjustments to be made. The danger is minimal, as fly back transformers are intrinsically low power devices, not capable of outputting lethal currents (due to the hair-thin secondary windings), and.....(circuit added 09/08)

Flyback Transformer Driver (Jonathan Filippi) - This is an efficient flyback driver for modern cylindrical rectified television flybacks. Many sites doesn't provide circuits driving these transformers, they simply say that they are bad.

Line Output/Flyback Transformer Tester - This is a 'ringer'-type tester I (Bob Barker) originally designed for in-circuit testing of Line Output (Flyback) transformers in TVs and computer monitors. After a couple of technician-years of evaluation in actual servicing situations, it's also proved to be helpful in locating shorted diodes, capacitors and deflection yokes in horizontal deflection stages. LOPT/FBT condition is shown on an 8 LED 'bargraph' display. (circuit / schematic design added 7/06)
