Product Description The Mini ZVS Induction Heating Board is a compact yet powerful high-frequency induction heating power supply module designed for DIY enthusiasts and educational experiments. Utilizing the Zero Voltage Switching (ZVS) flyback driver circuit, this module achieves high efficiency with minimal heat generation in the MOSFETs. It is capable of heating small ferromagnetic objects (like iron or steel) to glowing temperatures within seconds when powered by a 12V source. Beyond induction heating, this versatile board serves as an excellent driver for ignition coils, spark gap Tesla coils, and Marx generators, making it a fundamental tool for high-voltage and electromagnetic research projects.

Installation Tip from Robogears Induction heating generates extreme current; do not power the board for more than 5 minutes at a time without adding active cooling (a fan) to the MOSFETs and the heating coil. Ensure that the heating coil is properly soldered to the board before applying power; running the ZVS circuit without a load (the coil) can lead to immediate transistor failure. For best results, use a high-current power source like a Lead-Acid battery or a 12V 10A SMPS, as standard small adapters will drop voltage and stall the oscillation.
