I modified an old phone charger and made it output 30 volts then, I added a voltmeter screen to use it as a tester for measuring any LED or zener diode less than 30 volts.

  • These small switchers are invariably flyback types. Significantly raising the output voltage of the supply MAY result in damage to the switch on the high-voltage side. If you are using an AC line voltage well below the allowed maximum you are probably safe. If your line voltage is already near the maximum allowed, you could destroy the switcher. The secondary voltage is "reflected" back to the input side and "stacked" on the supply voltage according to the turns ratio of the so-called transformer when the switch turns off and the energy stored in the input winding is being transferred to the output winding. This is the only time that the inductor really acts as a transformer, and it is a design limitation for a flyback converter. Typically the inductor is designed so there is some safety margin between the sum of the peak DC on the input side and the reflected output voltage and the voltage rating of the switch. If you increase the output voltage it may result in exceeding the maximum allowable voltage across the switch which usually causes it to fail short-circuit. Another potential problem is that many of these switchers use an extra winding on the inductor to power the switcher IC after it initially starts. If the output voltage is set too low the IC may get insufficient voltage to keep it running, resulting in in shutting down, trying to restart, running for a fraction of a second (typically) then shutting down again.

I understand, pretty much, what each thing does, kind-of, but not together. Please do a video on HOW components do the outcome, together. My expertise was rewires and burn-ups on Locomotives.

  • Well at least it's not as deadly as some - but i'd still look at that transformer closer before using it. Also most phone chargers will have a '431 reference of their own, so modifications are either easier or harder, depending on the circuit... Finally, you should never push a transformer winding too far outside it's design voltage, as things get quite inefficient - possibly even dangerous! There is a reason why a relay clicks in the benchtop power supply; it selects three taps on the secondary winding - 0-7V, 7-15V and the final one goes to 30V... Simply looking at transformer action etc. should make it clear as to why it does this (hint: it's to do with 3Amp output current) Here there is a 10K? resistor, to limit the current - so the power handling is actually not bad...

  • Grand idea and useful point. I at first thought you were going to just make a adjustable power supply, but what you made was very good a testing device for Zener diode mostly or LED diode power value. I am still shocked to see the original power adapter have the possibility of 30 volts. I'm assuming that phone charger is a 5-6 volt power adapter, so that Zener diode had a lot of blocking to do. It is no shock these can still overheat. That voltage drop energy has to go somewhere....

    • I'm guessing that if this is a so called "universal input voltage" model, it won't make 30 VDC in the US. But you are right in that if it was designed like that, there's a lot o wasted energy and heating, built into the design. I guess it's easier and makes manufacturing simple, but it is inefficient. I'm in the US with the 120v 60Hz standard and I've seen a lot of issues with this universal input designs. Mostly, underperforming issues. I suppose the heat and efficiency issues are more likely in the 240V world. I hate looking at these kind of videos for a bit and then realizing what they are building was designed for the 240 volt world! I get that there are only about a billion of us using split phase voltage, 60 Hz in the100-125 volt range and that many more people have the 240is volt, 50Hz standard, but realistically, most of those people can't even read!! AW says it doesn't matter, but in many cases it does. Just my two cents, but electricity as distributed, is not universal. The physics works the same no matter where you live. But when you are modifying consumer goods for alternate purposes, one needs to understand that those items really are universal. Modification you make to devices in one country, very well may not work in another,

    • @@Inventor_AW Depends on how the charger is made. If it is a "universal input" type, it might, but the DC voltage out if the rectifier is going to be lower to start with. That's because the AC output of the transformer is lower. The DC is still enough so the charger still works but the max DC will be lower. You don't give a full schematic so I can only make some assumptions, But I would be surprised if you could get 30VDC output with a with a 120v input. You have some interesting ideas but they may well not work everywhere and might even prove to be hazardous.

  • essa pecinha azul serve para aumentar e diminuir a voltagem? por que tem um no AVR do meu gerador e eu aumentei e vi que mesmo ele em marcha lenta a energia ficou mais forte, só que não sei se isso pode estragar ele.

I don't know what was the amperage rating in your modified adapter, how it handled the 15v led bulb load 🤔 I've modified a laptop adapter recently, ratings was 19.7v / 5A. But when I increased the voltage amperage goes lower, and when decreasing the voltage it's came to it's full amperage 5A.

  • This is a super cool device that I would have had use for recently! Instead, I took LEDs of differing voltage ratings and a whole bunch of resistors to make them equal brightness. Question: how can this circuit measure the "voltage" of an LED, which obviously can be safely run at different voltages? How does it find the nominal or ideal voltage?

    @quipstad@quipstad9 ай бұрын

    • A semiconductor PN junction has a certain forward voltage, depending on physics and chemistry. If you apply a rising voltage to it in the correct direction, nothing happens until that threshold voltage is reached and then current starts to flow. Raising the voltage will dramatically increase the *current* flowing through the junction, while the voltage across remains fairly constant, until it overheats and dies. Here a 10k resistor is put in series to limit the maximum current. The 30V is high enough to turn the PN junction on, which then remains at its forward voltage, with the remainder dissipated across the resistor. The voltmeter simply measures across the PN junction, showing the forward voltage, which is relatively independent of the current.
