The totempole driver charges the mosfet gate almost instantaneously by charging it with greater current and providing minimal resistance.

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. The 10 ohm resistor charges quicker, much quicker, and so, the rise time is very small as compared to the 2k resistor which limits the current, thus making the capacitor take longer to charge. I spent a lot of time for finding resonant frequency around 15khz and duty cycle. Posted on july 27, 2015 july 27, 2015 by katzmanverde. I wanted to do a audio modulated flyback arc with few components and a small form factor. Phase dimmable, primary side power regulated, pfc flyback controller for led lighting. Issuu is a digital publishing platform that makes it simple to publish magazines, catalogs, newspapers, books, and more online. Since all you lazy fucks didnt want to build a zvs driver, heres a way to make high voltage easier.

Back in 2008 before starting with high voltage, i have made numerous experiments with.

This driver rectifies mains and produces a 320v dc source. This is a fairly configurable and very durable flyback transformer driver. This single transistor flyback driver topology was created in response to achieve. This circuit, also incorrectly known as the 2n3055 flyback driver, bears some resemblance to the battery invertercontinuity tester which is published here.

Led driver plays an important role in unleashing many advantages of led, such as high efficiency, long lifetime. As well as the complexity and extra cost, i suspect that the high voltage field may leak into the arduino and kill the delicate processor, or. The first video demonstrates the high voltage arcing through a beercapful of beer stella artois with a power supply voltage of 9v. We built it because my boys want a tesla coil demonstration at their school.

Since all you lazy fucks didnt want to build a zvs driver, heres a way. 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. A friend at purdue university sumanth peddamatham helped motivate and inspire me to create a high voltage flyback transformer driver for a computer crt flyback.

I installed the mosfet on a old cpu heat sink with fan, the 555 timer circuit is also installed underneath this heat sink, its then all put on the side of the flyback transformer with wire strips.
