If you have ever built a flyback driver or a solid state Tesla coil (SSTC) , you have probably wrestled with MOSFETs.
Without zeners, the resonant tank can swing the gate voltage to 30V+. That will puncture the gate oxide instantly. Use 15V bidirectional (back-to-back) zeners. The Schematic (The Classic IGBT ZVS) Here is the proven recipe for a 200W+ IGBT ZVS driver: igbt zvs driver
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. If you have ever built a flyback driver
They get hot. They explode under slight over-voltage. And if your gate drive is weak, they simply refuse to switch fast. they simply refuse to switch fast.
