From the project
Open Source Hardware 470KHz Induction Soldering Iron
The power supply is the core of the 470KHz system. It is based upon a class-E amplifier and contains impedance matching circuitry to properly provide power to the soldering iron tip.
The provided PCB design includes all basic functionality needed to operate a 470KHz soldering iron tip.
The design includes provisions for inrush current limiting, reverse polarity protection, a cooling fan, and two different types of oscillators. The inductors, apart from the fixed 33uH inductor, are all based around the Kool Mu 0077932A7 core, which is currently only available from Digikey, though we are…
