High voltage LFO and voltage multiplier

Created through trial and error. The first voltage pulse is input manually with the button. This then controls a MOSFET, letting current go through a (step up?) transformer. On the secondary side of the transformer there’s a capacitor, forming a tank circuit. The sinusoid output of the tank circuit goes through a zener diode go keep the voltage regulated. This signal is sent to a BJT which operates as an inverter. (I also added a regular diode here to ”protect” the BJT). The BJT produces a square wave with the same frequency as the tank circuit. This square wave goes through a MOSFET which also acts as an inverter. Finally, this signal is sent back to the first MOSFET, producing a self-sustaining oscillation. I have no idea if this is a realistic circuit or if it’s a weird implementation of some very well known circuit that I should know about, but hey, I’m a biologist not an engineer. I also added a little voltage multiplier for fun.

you do know you just need a coil and capacitor at the same values in series and just pules it with a PWM at is resonant frequency witch depends on the values and you can get 40v and 40 amps if you are pulsing in with 9Vs. but you know that already right?

@dragoola, I’m not sure if i know that, lol. I’m just messing around. I’ll try it out! Thank you :)
