    This circuit is absolutely NOT isolated from house line. If input voltage is 220vac, the output will be about 110vac vs ground/earth, and quite fatal.
    Anyway you can make it more effective. Behind the capacitors should be a full-wave 4-diode, with zener and rectifying caps at output. The circuit then can provide max current 60mA at 220v (using 2x225 cap)

      If you want to use with MCU then you have to use Opto Isolator to protect the MCU circuit. A better approach is to use a 1:1 Isolated transformer.

    • @ngusi1st
      @ngusi1st 2 года назад +3

      @@mohanmovibrothers3539 The current going thru the cap can be estimated as of 70mA per 1uF. Simply it comes from the formula Zc (Ohm) = 1/2(pi)(Freq)(Farad), applied for V=220vac and Freq=50Hz. So you need a 15uF for your demand. Out-voltage relies on resistance of the load 5V 1A means load is about 5 Ohm, otherwise clamping it with zener circuit

    There are a few thins wrong with this circuit:
    1) the zener diode should be AFTER the power diode 1N4007.
    2) the resistors are rated 200V max.
    3) the resistors make it not an isolated power source.

      The capacitors are also not rated for use on AC mains voltage; normally, such capacitors will have markings from various safety agencies to show that they are rated for that use.

    • @erikdenhouter
      @erikdenhouter 2 года назад

      Zöld Prespán pointed out that the zener IS in the right place, otherwise there is no discharge of the caps. A bridge rectifier would be much better, and then place the zener over the filter cap.

    This is nice circuit to use as power failure detection circuit. You may connect the output to an MCU via Opto Isolator and create your own algo that responds accordingly to power failure. I did similar circuit to this using old transformer which detect power failure with alarm sound of 2 x AA batteries when power fails. This is because someone turns OFF the main power to disable all alarm and camera systems, you can be warned once someone shuts down the main AC power from house main pannel. You may then use an IP wireless transceiver to boradcast the power failure signal to remote location and confuse the thieves and intruders with alarm sounds from unknown locations.

    This is not isolated! I understand there is no galvanic connection because the capacitor includes an isolator between the conductors, but current still can flow through your body to earth if you touch the low voltage wire. This is more dangerous then the original dropper (if the neutral is the common), at least the zener clamps the volage to the neutral there.

      ​@@erikdenhouter The zener is at the right place. Because the capacitor has to drop AC , not DC (there is no reactance at DC). In this case the current can flow through the zener both ways so you have AC. If you put the rectifier diode before the zener, the current can flow only one way, so you will charge up the capacitors with DC, then nothing happens. But, if there is no common neutral (to handle triac for example) it would be much better to use a full bridge rectifier, to double the power.

      @erikdenhouter 2 года назад +1

      @@zoldprespan2389 You are right I think, I forgot the negative pulse to have a path. For that I would, as you also stated, rather use a bridge rectifier, it makes it also more efficient so you could use smaller caps for the same power needs. And then the zener would be placed correctly after the bridge, just parallel to the filter cap.

    И где же тут изоляция от сети? Через конденсаторы всё равно ток частично проходит (на этом принципе и основана схема). В целом, схема годная для каких-то ситуаций... например, для маломощного светодиодного фонаря. Однако, я бы поставил нормальный диодный мост и электролитический конденсатор ёмкостью побольше. Это бы избавило от мерцания света и сгладила скачки напряжения при включении в сеть.

    Of course it is uninsulated. But this is just such a power supply. You have to use everything wisely.
    Not every receiver can be connected to this power supply. LED diodes with controlled current as much as possible.
    There is no point in building a more expensive power supply to power the LEDs. Many things can be improved depending on what it is for.
    I would just take care of some insulated housing before connecting this power supply and add a fuse just in case.

      @@zoldprespan2389 do not be jealous bro at least he did his best and made something new. it is isolated supply because it uses two balanced network to avoid shock and rest of work did zener and output load. anyway u can try it. although science is all about experiments and thesis.

      @@Engineer.Critics I'm not jealous. In this circuit there are the following components is series between the Line and Neutral: capacitor, zener diode, capacitor. So both capacitors drops about 100V. If you touch the low voltage side, you will be connected in parallel with the neutral side capacitor (because the neutral has the same potential as the earth) so you will touch about 100V.
