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.
IGBTs have larger gate capacitance and a lower maximum gate voltage (usually ±20V). The standard ZVS driver uses a 12V or 15V zener diode across the gate. For IGBTs, you need a 15V or 18V zener, and you need it.
While the classic "ZVS" circuit (the famous Mazilli driver) typically uses MOSFETs, swapping them for transforms this oscillator into a nearly indestructible powerhouse for high-voltage projects.
Enter the .
Build it ugly. Build it strong. And always discharge your capacitors before touching anything.
They get hot. They explode under slight over-voltage. And if your gate drive is weak, they simply refuse to switch fast.
