High Voltage ZVS Driver

Welcome all technology science lover .
First thing, this is very dangerous for yourself please make sure you are safe.
ZVS Flyback driver can make 20,000 volts 20kV.  You can also put Marx Generator who combined with .27uF, 1200 volts. This is 555 timer based ZVS and that's why we can also input audio in  pin 5.
The mosfet transistor in this project use for (IRF 250). The total cost of thing is 12$ to 15$.
Working Principle

Flyback transformers are found in monitors, TVs or anything with a CRT, and are sometimes known as Line OutPut Transformers, or just LOPT. They are used for generating high voltage for the CRT, which is needed to create an electric field, which in turn accelerates electrons towards the screen, which finally excite phosphors and create the image you see. Flybacks are designed to work best anywhere between 15 to 150 kHz, so some experimentation is required to find the intended operating frequency. TV flybacks are generally designed for upper audio frequencies, which is the cause of the high pitched noise heard from a muted TV. (If you're over 40 you will need to confirm this with your kids.) The optimal operating frequency can have many harmonics, which will work as well as the actual optimal frequency to some extent. Since flyback transformers use a ferrite core they need vastly different operating conditions than an iron cored mains transformer. In fact flyback transformers aren't really conventional transformers at all, but coupled inductors which means they should be driven differently. Fyback transformers are generally either driven in "flyback mode", or some push-pull topology. The first two drivers on this page drive the flyback in flyback mode, while the last two use push-pull topologies. To obtain a high frequency variable duty cycle drive signal we can use the 555 timer. This simple driver circuit is quite efficient if tuned correctly, and in some cases quite powerful. It is currently set to run between 17-50 kHz, which should be a large enough range to sweep through any harmonics a flyback may have.

Know More for 555 Timer

The 555 timer comes as 8 pin DIP (Dual In-line Package) device. There is also a 556 dual version of 555 timer which consists of two complete 555 timers in 14 DIP and a 558 quadruple timer which is consisting of four 555 timer in one IC and is available as a 16 pin DIP in the market.

 1. Ground: This pin is used to provide a zero voltage rail to the Integrated circuit to divide the supply potential between the three resistors shown in the diagram.
2. Trigger: As we can see that the voltage at the non-inverting end of the comparator is Vin/3, so if the trigger input is used to set the output of the F/F to ‘high’ state by applying a voltage equal to or less than Vin/3 or any negative pulse, as the voltage at the non-inverting end of the comparator is Vin/3.
 3. Output: It is the output pin of the IC, connected to the Q’ (Q-bar) of the F/F with an inverter in between as show in the figure.
 4. Reset: This pin is used to reset the output of the F/F regardless of the initial condition of the F/F and also it is an active low Pin so it connected to ‘high’ state to avoid any noise interference, unless a reset operation is required. So most of the time it is connected to the Supply voltage as shown in the figure.
5.  Control Voltage: As we can see that the pin 5 is connected to the inverting input having a voltage level of (2/3) Vin. It is used to override the inverting voltage to change the width of the output signal irrespective of the RC timing network.
6. Threshold: The pin is connected to the non-inverting input of the first comparator. The output of the comparator will be high when the threshold voltage will be more than (2/3) Vin thus resetting the output (Q) of the F/F from ‘high’ to ‘low’.
7. Discharge: This pin is used to discharge the timing capacitors (capacitors involved in the external circuit to make the IC behave as a square wave generator) to ground when the output of Pin 3 is switched to ‘low’.
8. Supply: This pin is used to provide the IC with the supply voltage for the functioning and carrying of the different operations to be fulfilled with the 555 timer.
