Many sites doesnt provide circuits driving these transformers, they simply say that they are bad. Flyback transformer driver this is an efficient flyback driver for modern cylindrical rectified television flybacks. The zvs flyback driver it is probably the most powerful and efficient. Or you can use a secondary with only a few turns of tick cooper wire, to get a current so high, that can melt thin copper wires connected across the output. Mar 16, 2012 this single transistor flyback driver topology was created in response to achieve higher efficiency and higher output voltages from ordinary crt television flybacks diode split flybacks, for experiments such as xrays or ionic lifters, without having to make any external hv multipliers. Mar 14, 2015 i have also included inductors used as chokes to suppress any voltage spikes from the driver circuit. Finally, i have put two inline diodes to stop any ac currents flowing back up from the driver circuit. Jul 20, 2008 so for my first real flyback driver, i built a dual 2n3055 transistor based flyback driver. This circuit, also incorrectly known as the 2n3055 flyback driver, bears some resemblance to the battery invertercontinuity tester which is published here. Flyback driver with mosfet z44 make 0 volt new project duration. The last part of the circuit is the flyback driver circuit as seen previously and is separated form the dc supply via a switch.
Back in 2008 before starting with high voltage, i have made numerous experiments with flyback transformers and with simple singletransistor drivers, most of these were undocumented. It is the same topology with almost the same efficiency, and its actually a nice example what happens when a primitive circuit like this is used with slightly bigger input. This is an efficient flyback driver for modern cylindrical rectified television flybacks. You may also use the zvs flyback driver with a ferrite core and a custom made hv secondary, see this article. Como hacer transformador flyback ingenieria electronica.
This single transistor flyback driver topology was created in response to achieve higher efficiency and higher output voltages from ordinary crt television flybacks diode split flybacks, for experiments such as xrays or ionic lifters, without having to make any external hv multipliers. Flyback transformer driver circuit diagrams, schematics. I used a long terminal strip to arrange the resistor components. The gist of it is that while one 2n3055 overheats very quickly, 2 paralleled 2n3055s will be able to split the current load and avoid overheating too rapidly. So for my first real flyback driver, i built a dual 2n3055 transistor based flyback driver.
