Hi All,

Would any one out there be willing to do a short explanation of how this circuit operates?

I have the circuit set up on my bread board and it is working somewhat. The main issue is that the connection to the negative of the charge battery is not being fully disconnected (as should happen when the FETs shut off). I'm pretty sure this has to do with what's happening at the comparator but I'm unsure of what the voltages on the + and - should be as well as the supply voltage to the comparator.

Is the circuit powered just from the charging capacitor? I would have to assume so since the charge battery is only connected to the circuit during the time of the pulse.

Any light that could be shed would be awesome!

Thank you!
