This is a public thread for STEAP and the TPU (Steven Mark). It has taken me a long time and a lot of money to find out how this works. Most of this I have published before in a private thread, but this time I will not make you work for an end result, the missing links will be explained. What I post are SCHEMATICS and not always a working electronic diagram, what you get is the principle of function, the rest you build yourself. The first thing to remember is C1 is made up of the solenoids wound over the loop CORE (ground plate of a capacitor). The solenoid coils form the other plate, there is no induction between the solenoids and the CORE COIL, it is a varying capacitance, a very special capacitance. SM probably used all P-type MOSFETs, but I use N-type and MOSFET "B" is high side switching. C2 is that rather expensive HV capacitor seen in his videos. The switching sequence is such that "A" and "C" are never ever on at the same time as "B", timing is everything as SM said. The D blocking diode is representative of two diodes at the positive end of the charge chokes. The run cap is just that, you charge it to start the generator, you need an automatic safety switch to turn this OFF (temperature and over-voltage). Please note the connection sequence of the solenoid coils, remember they go around in a toroidal shape. The discharge curves are representative only, in the real unit running there are multiple HF resonances between charges, so many they overlap. Regards Mike
