iwire, the simplest solution would be to just insert the required calculations in and viola, you’ll be good to go. If you want to understand the algorithm you’ll have to read the paper that basically explains that. I’m not sure if the people who wrote the software would eventually tell anyone...
What is your target output for your circuit? Try using a a regulator or a pot to stabilize your output voltage. This way you cannot have a problem when you put a load on your DC power supply because your output voltage is now regulated. It cannot have a voltage dropped when you do this.
