Voltage Boost

Good job

Wow

How works?

I'll explain it as best I can but to be perfectly honest I made this circuit while just playing around with the circuit sim and partly got lucky with how it turned out (sometimes you can discover some neat stuff when you quit planning and just start sticking a thing in a thing and couple it to another thing in parallel with a thing....). So there's a lot going on in this circuit I don't fully understand but the basic principles behind it are Faraday's law, Lenz's law, and Inductive reactance. When the switch is closed, the primary coil of the transformer is energized, meaning current is flowing through the coil and it has a static magnetic field around it (I'm skipping a few things that happen between the switch closing and the current flow through the inductor becoming constant but it's not really important). Now when the switch is opened, the magnetic field of the primary collapses; Faraday's law states that a conductor present in a changing magnetic field will have a current move through it as a result of, what we call, induction. Lenz's law states that the current will flow so that it's own magnet field will oppose the change in the magnetic field originally responsible for inducing it. This means inductors will resist changes to the flow of current; this property is called inductive reactance. So the current in the primary wants to keep flowing without change after the switch is opened so the voltage increases across the primary which is stepped up to a much larger voltage across the secondary which charges the capacitor. Because the input cap forms a tank circuit with the primary, it'll oscillate for a short while after opening the switch so we use the diodes to rectify alternating current from the secondary. I hope that helps and if anyone has anything to add or if im mistaken anywhere please comment and share what you know.
