Well the saga continues..... (formerly known as inductorless SMPS)
I've brought my design up to scratch a bit and have managed to factor in a real world MOSFET. the only thing I can't understand is why increasing the capacitor size increases the tendency to oscillate a bit.
If I understood correctly the operating frequency should be higher than the LC resonant frequency, how do I acheive this ? I'm begining to think that its the LC resonant frequenct that to some extent is controlling the frequency that the circuit works at.
Reducing the load resistance actually descreases frequency although i assumed the oposite as surely the circuit has to work faster to supply more current.
again this is a theoretical model so feal free to bash it with real life expectations
