Hi friends, I was asked many times what kind of generator was used in the video about whining of the high voltage transformer. I used a simple push pull oscillator circuit, or the so-called ZBS driver. It is also often used in amateur structures of induction heaters. This scheme is so popular that there is lots of Chinese production. Below the video there are several references to buy ready modules. There are several variants of this scheme. We consider the case with the average point of the coil. In my opinion it's a bit more stable than two chokes without midpoint. In fact it is a resonant converter, which was built as a generator. Here each arm of the circuit must be treated as a separate oscillator. The optimum power supply voltage is 20 volts, although worked from 3.5 volts. Power supply should be sufficient to trigger the FATs. I used the N channel IRFZ44. The torque is taken from a computer at EX power supply. Core is made from iron powder. Gate resistors have two functions. They simultaneously limit the gate current and the current of the zener diodes. The zener prevents voltage increase through gate and protects FAT from breakdown. They maintain a stable operating voltage. Although experience shows that when powered from a stable source of 20 volts, no need for zener. The transformer primary winding is connected in parallel with the capacitor to form a resonant circuit. By changing the parameters of these components, the working frequency of the generator can be changed. As I have said before, the scheme often used for constructing simple induction heaters. Although it is not an optimal due to the absence of the scheme for FATs regulation. And good oscillator. Large currents flow through the circuit and capacitor is also operates in hard conditions. Particularly if the circuit is used as an induction heater, i.e. if the core is absent or it is not closed. Therefore I advise you to use battery of capacitors connected in parallel with the total capacity of 1 to 4.7 microph. And voltage of 630 to 1,600 volts. Optimally is 1000 volts. Practice shows that 400 volts not enough. In the case of the capacitor bank, all should have the same capacity and voltage. Simple but powerful high-volt generator can be constructed on the basis of this driver and the TV fly back transformer. With 3 part of the core due to 2 at 5 or 2 at 6 turns of wired with a diameter of 0.8 millimeters, I advise you to use standard copper wire with silicone insulation. If you use a fly back transformer from an old TV, be sure to fill additional resin on high voltage winding. Otherwise, the transformer will burn. Now let's look to device capability. As the power supply, I use screwdrivers 18 volt nickel-cadmium battery. In the next video, we examine the pros and cons of this scheme. In some, the next videos, we examine the pros and cons of this scheme its limits. And we will assemble Tesla transformer. All additional information can be found under the video.
