Hi all,

While messing with buck/boost circuits I had some thoughts which don't
hold up in real tests....

A simple example (aside from losses) is that if transfer energy from
say 10V 10uF into 1uF the voltage will increase to preserve the
charge.

Now, in my circuit, I charge 25V 1,000uF capacitor and charge a 10uH
inductor. When the switch turns off, all the energy should be in the
10uH inductance. So if I have a 100pF capacitor, then the voltage
should be like 100,000volts according to my workings out.

Now I ran a computer simulation on this, at best I can only obtain
12KV on the 100pF. So most of the energy is lost in switching losses I
assume.

In realworld tests, I end up with less voltage than I started out
with, So I am trying to find out why ?

I know charging 22uH inductor at 100khz can be used as a buck/boost
supply, I built a simple 12V to 30V inverter, can switch 10amps
easily. Though I am not running at 100khz, only 100hz. Though the
current pulse rises to something like 500amps over 500uS.
