I am working on a transformerless PSU for maiking a 3nos.x3 watt led, each having forward voltage around 3.6v and current around 650-700ma. I have worked on this kind of circuit: I guess a 1uf ...
Is it possible to convert 240VDC from 20*12V batteries to 180VAC-240VAC pure Sine Wave? i have an idea using H-Bridge mosfet drivers....But i have seen on web that 350Vdc is must to convert it to ...
I just let the smoke out of my testing setup. I designed and built a simple power supply using this guide. I built a capacitive power supply with a bridge rectifier and a final 3.3VDC voltage ...
I'm trying to put the CS5463 chip functional using the example circuitry on page 41 of the datasheet (attached bellow): Right now, I'm working on the top part of the circuit, which is the IC power ...
I'm working on a circuit powered by a capacitive transformerless power supply, that is a microcontroller based triac-switching project for resistive loads. I've taken the basic design of the power ...
I want to power a single 3 mm LED by a 220V AC source. For this I think I need one LED, one resistor and one capacitor. I don't know the needed resistor value and circuit diagram. The circuit also ...
Something like this Falstad sim version of it (I'm tired, I keep making mistakes, so please excuse me for the second time.) Now these are not very safe PSU's, due to the lack of isolation. But in ...
