0-30V varable volatge regulator


Recommended Posts

sir,
I need 0 to 30 V VAriable power supply design using UA 741 as the current limit and another 741 as a voltage limiter.
I already have one circuit. In that the 723 provides the supply for these two 741s only. and the 10 th pin in the 723 drives the a transistor which control the output voltage. Here i used three 3055 transistors to drive the load. But in 5V-1.5A loading the transistor was very musc dissipate the heat enenthough with a heavy heat sink. Here one doubt is each transiustor is rated to 120 Watts.

gaark, if you can attach a schematic or a link to the circuit you are working on, it would be helpful to others to see what you already have in the circuit. I have noticed that the posts which get the most replies on this forum are those with an example attached. It makes commenting easier.
