Let’s break down why you need this, how it works, and how to build one that won't burn down your workshop. First, a quick recap. The Zero Voltage Switching driver is a resonant oscillator. Unlike hard-switching circuits that turn transistors on while current is flowing (causing heat and spikes), the ZVS turns the transistors on only when the voltage across them hits zero .
Enter the .
If you are tired of replacing MOSFETs every time you sneeze near your flyback, the IGBT ZVS driver is your solution. It is slower than MOSFETs (so don't use it for MHz range), but for 20kHz-100kHz high-voltage work, it is bulletproof. igbt zvs driver
