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

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
