NNNI Lol, sub'd, prove it ;) At first glance, I was wondering if I could rig a FET to replace that power NPN and use the Vgs resistance as a replacement for the power resistor but I will need to play with that one in a simulator first ;) I know the 2.4v zener should be replaced with a TL431 as the first step to building this easier with junk components ;) -Jake

Dear Kasyan, Please consider spending more time explaining each circuit as you would in a class room environment. With current paths and voltage states. Many of your viewers are experienced in electronics (like myself), and will not learn anything new, but far more numbers are learning the ins and outs of electronics and will benefit greatly from such analysis.

Hi Kasyan. It is a very good project. I tried to make it but there is one problem when I turn down the ampares to zero the half voltages still shows like I tried with 18v transformer. When I turn down the 100k pot to zero and turn up the full the 10k pot voltmeter shows 8.5 voltages and the voltages also moves with ampare pot. Please guide me what can get wrong?

@iblesbosuok6 жыл бұрын
Zetsubou_232_ , ofcourse it is possible. Applying typical dimmer on primary side of the power transformer, apply additional snubber network on the triac and apply small resistive load in parallel with the primary will work fine. Unfortunately it not provide regulated output voltage.

If you substitute D3 with TL431, the output voltage will be much more stable.
