Yes you are right.
However I chose to work on the primary side to work with smaller currents. To recall the secondary triac/mosfet/transistor to be used must handle at max 35Amps. I think it is easier to control the primary with a tenth of the current though voltage levels are much higher...
Thanks for your reply RussMartin and em2006.
Dear RussMartin, I need to check more about this chip as I have read that it is not suitable for inductive loads such as transformers. But defenitely worth a try.
Thanks em2006 for your suggestions. I have amended drawing and would like if you...
Hi all,
This is my first post though occassionally I read most interesting posts.
I need to build a 1-35Amp (max voltage 35v) constant current source for Anodising Alluminium purposes. I have experimented with PWM on the DC side etc but on small loads <0.5R the circuits did not give adeqaute...
