High frequency soldering station V1.0

Royer oscillator ZVS main power topology, high-side MOSFET large period control power adjustment. Depending on the handle and soldering iron tip, the frequency is between 500kHz and 600kHz. The maximum power of the soldering iron tip of the 203H handle is close to 200W when it is cold, and about 150W when it is hot. L1 needs to be customized with a carbonyl iron powder magnetic ring, L2 is an iron-silicon aluminum magnetic ring, the transformer has 5+5 primary turns and 27 secondary turns. The car power amplifier transformer can be customized by changing the number of secondary turns. The resonant capacitor is not shown in the picture. It requires a 47nF, 1600V or 2000V withstand voltage CBB81 (or other low loss tangent capacitor). Q1 and Q4 actually use 2sk2260. People are lazy and haven’t written the code yet.

The L1 inductor uses a T94-2 magnetic ring, with three 1mm or 0.8mm windings. The inductance is 4-4.7uH. You can find a shop on Taobao to customize it. The material cannot be wrong.
