Who would like to beta test one of my new voltage regulators?

Been researching a playing around with a charging system model I found on a forum with spice a bit.. I had never really spent anytime understanding how these really worked... I get it now. They are just bang bang type controllers so they are inherently stable... I did read that modern regulators run constant PWM and vary the duty cycle. There are also other considerations for off nominal conditions like startup and recharging the battery running full alternator output for a significant amount of time putting undo stress on alternator diodes, bulk head connectors, etc.

The frequency really ends up being variable depending on the capacitance of the battery, load and peak charging current. You mentioned running the frequency too high, are you running fixed freq and modulating duty, it does not seem like the PWB photo had enough components to do that?
