Circuit ZVS driver induction heating mosfet IRFP260. ZVS induction heating has the characteristics of simple structure, high power, wide range of uses, low cost, easy to start with zero threshold, cheap and easy to sell. This post will provide engineering files and parts procurement list for ZVS induction heating, simple and easy to copy, as long as you have hands.
The open source license for this project is WTFPL! Declaration: If you use this thing to get into trouble, or if you get into trouble yourself, just bear it yourself, I am not responsible for anything. If you sell ZVS and lose money, don’t blame me, if you sell ZVS and get rich, you don’t need to thank me.
The 2-tube ZVS induction heating, the power tube model uses IRFP260 field effect tube, working under 48V (53.5V), can run at a maximum of 1.5kW.

Board
Full kit:
- Copper pipe
- 48V Fan
- Water diaphragm pump + power supply
- ZVS driver board
- 24 at 48V 30A power supply for ZVS
If you intend to offer ZVS for sale, it may be advantageous to consider purchasing in bulk. Water pump, you can buy a diaphragm pump on AliExpress with a power supply.
Fan, buy a 48V 12025 or 12038 high-speed fans. Pay attention to the positive and negative poles of the fan, do not insert wrongly, and do not use metal fans.
About the selection of power supply, you can find Huawei R4850 or R4875, ZTE ZXD3000 or ZXD4000, Delta 4856. This thing is available in both new and old versions, depending on your preference.
Regarding the heating coil, if it is used for crucibles, then buy the crucible and wind the copper tube on top of the quartz crucible. If used for heating other workpieces, do it according to the actual situation. The larger the diameter of the coil, the more turns, the greater the power required.
Generally used for heating workpieces with a diameter of less than 60 mm, pay attention to coupling during heating, and monitor the current to avoid overload.
Crucible selection: You can buy a 1kg crucible set on AliExpress, or use the following small crucible.
Small crucible specifications: You can directly contact the purchasing address to customize. Quartz crucible specifications as shown in the figure.
Graphite crucible drawings are as follows
