Hi, guys, I just find this page, and is an amazing one. ;D I've got a problem with this kind of circuit, I'm thinking a dimmer could solve the problem, just one thing, I need to control the power from 0-100% with one voltage input of 6.67V max, so I want to know your opinion, if you think that a dimmer of 15A would work fine or some other circuit, I thought also of a saw tooth signal with a reference of 6.67V max controlling a Triac based circuit :-\. If you can aid me with circuits diagrams I would be pleased, thanks. :)
