Igbt Zvs Driver May 2026

Build it ugly. Build it strong. And always discharge your capacitors before touching anything.

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 .

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. igbt zvs driver

If you have ever built a flyback driver or a solid state Tesla coil (SSTC) , you have probably wrestled with MOSFETs.

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. Build it ugly

Enter the .

They get hot. They explode under slight over-voltage. And if your gate drive is weak, they simply refuse to switch fast.
