Voltage Regulator

Full wave bridge rectifier with 2 channels, 2 voltage regulators. Potentiometers vary the output voltage.

Current limiter keeps current under 1A; LED turns on when current is being limited.

Very nice! One tip though, the pot controlling the output voltage is too large! In only from 0% to 20% of the pot the output varys. 25% of 100k = 25k. Change it like that and you'll get the full output range from about 0V to 15V with a full single turn.

Thanks, kaivanveldhoven, I didn't notice that until I soldered it up. I replaced the lower resistor with a 4k since that was cheaper than replacing the pot.

Hi bt, Good ckt. Of course we don't want to ground the ac source to dc ckt ground. The problem is the ac source will not work in EC unless it's grounded. Here's how I get around that. Remove your ac ground. Remove 1 of your ac sources. Just have 1 ac source connected to both xformers. To make the ckt work, ground the lower side of the AC source to ground thru a small capacitor. I often use 10 nf.
