    Convert 0-30V 3A PSU to 5A or more

    Hi, I am Gaark. Thank you for your response about the variable psu.I read your discussion on the PSU only in the transistor/heating phenomena.If yo need to arrest more heating, one of the easiest way ( other than using any mechanical ) to simply control the AC input voltage to the...

    0-30V varable volatge regulator

    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...
