Snubber capacitor calculator

Here you can calculate the snubber capacitance that is needed to keep transient voltages below the maximum allowed value. Stray inductance is the inductance in the primary circuit of the inverter. If the stray inductance is not known, the two … Continue reading

TL494 flyback driver

It took some years and someone recently bumping up my old thread about this project for me to write up a article, find the pictures, make a video and get it on here. Read all about the design and construction … Continue reading

TL494 flyback driver

Introduction I wanted to design a versatile driver circuit that could drive a half- or full-bridge of MOSFETs or IGBTs through a gate drive transformer (GDT). This should make a driver that is able to run flyback transformers found in … Continue reading

Kaizer SSTC I

Introduction This is my first solid state Tesla coil, so I went with a sturdy and proven schematic made by Steve Ward. A lot of other coilers have replicated this circuit with great success and therefore it is easy to … Continue reading

555 Audio modulated flyback

Introduction This is a audio modulated arc generator designed for simplicity rather than reliability, its made with very few and common components. There is however some serious trade offs described below in considerations. WARNING: sensitive audio players might get damaged … Continue reading
