I am building a high power ZVS induction heater. I originally used this famous design. It worked like a charm when I used a 48v 31A power supply. But I want an upgrade. I recently got a few of these FCH072N60F 600v 52A power mosfets. They have a low Rds on, fast switching and low gate charge. All of which are needed for a good ZVS driver.
However, I recently got myself a 96v 30A power supply. I simply replaced the IRFP250N mosfets with the beefier FCH072N60F mosfets. I then realized that at double the voltage, my mosfets would burn out. The 470Ω 2w resistors were for the 48v version.
Could I simply double the resistance of these resistors or is it not that simple?
