Flyback transistor driver

Try the Mazzilli ZVS flyback driver! This driver is capable of pumping upto a kW of power, so impressive arcs can be made. Normal operation from 12V only results in about W, but that's still several times what the drivers will process. Flyback preparation: Get your new flyback ready for use. Circuit 1: Ultra simple Single Transistor flyback driver circuit. - Parts you will need, and how to get it working *updated!*. Circuit 2: An even simpler circuit if you have a SMPSU. Testing and Results: Pictures and Videos of experiments *updated!*. 1 2N NPN transistor, with complete mounting kit (2 plastic spacers, bolts and nuts to hold it in place, mica insulator, and thermal compound). 1 Large heat sink for the transistor. 1 Ohms, 5W resistor 1 27Ohms 1W resistor. Flyback, hookup wire, solder, soldering iron, etc.

This is a instructable that contains scematic and pictures of a single transistor flyback driver. stuff's used: 1x breadboard 1x NPN transistor (with heat sink and a fan) 1x 22 Ohm resistor 1x Ohms resistor 1x transformator (or round ferrite core) with same amount of windings 1x flyback transformator 1x 12 - 15V Powersupply (i use a battery that gives 15 volt, mA) And some wires. Flyback driver #1: Single transistor driver. March September - High voltage. Back in before starting with high voltage, I have made numerous experiments with flyback transformers and with simple single-transistor drivers, most of these were undocumented. However, this was one of my very first high voltage circuits and my. 1 2N NPN transistor, with complete mounting kit (2 plastic spacers, bolts and nuts to hold it in place, mica insulator, and thermal compound). 1 Large heat sink for the transistor. 1 Ohms, 5W resistor 1 27Ohms 1W resistor. Flyback, hookup wire, solder, soldering iron, etc.

Here's the classic circuit im using: [IMG] It's made to create high voltage AC from DC. I've killed a few transistors with overvoltage using. As mentioned above this driver drives the flyback in flyback mode. What that means is that the mosfet is turned on by the timer, and current starts to flow. The output voltage from the ZVS driver and flyback transformer to the plasma torch (quartz tube) was determined using Falstad circuit simulation. The.
