 Hey guys This is just a little elaboration on the on the voltage doubling circuit No, I Did use the center tap and made this a dual power supply But I'll just come back to the voltage double F because we've already got 14 volts Coming from this AC What if you needed like, you know 30 plus volts what if you needed 35 volts from it? Is that possible? Yeah, I mean it's we can we can do the variable of course, so it's the voltage doubling circuit No problem, and then we just we check on a NLM 317 This one is an LM 317 HV Which is the higher voltage. I think this one goes up to 50 volts I'm not sure but look I'll just check on a little thing down there We got the minimum I mean we can make that smaller we can definitely make that smaller we can just take a Stick a couple of diodes on the output Yeah, there are two diodes to do it on the output. This thing's 1.5 amps. So stick a couple of 223 amp diodes on there And it will drop the voltage enough to bring that down to zero If they're 0.7 each, you know, we're bringing that down to pretty much zero if the forward voltage was 0.7 volts On the diodes, so basically now we've got a little voltage doubling circuit and we can turn this up And up we go So that's past what we get from the output of that little transformer We just keep getting up that's 30 volts 35 6 And that's it that's it So you've got 26.6 volts of course we had to lose a few volts across the regulator there Smallest That's basic rule circuit now really, you know an orphan has to actually use this circuit. You know you wouldn't be able to I don't think for a lot of things You know with some capacitors You might even want to stick a diode and from the output of this to the input Just make sure anything that comes back from that capacitor doesn't try and kick in the doors of the output Just gives it a little circuit back around Which year Just elaborated on the It's not the dual splite was it? No, it's a voltage doubling circuit Had to build something quite similar For a power supply for this thing here Because I didn't have one that would work so I have to build a little voltage doubling circuit for that and then regulate it And mmm, but it just give me enough power to get it to work So it's just a quick just to show you what actually happens when you put a bit of a load on it No, it's just this fan This fan is set. So I think it's like 11 and a half volts on that little buck converter on the top there So we're gonna expect that to use a little bit of the voltage we're gonna expect the The LM 317 I must have the HV to that Because it's a bit of a special I'm actually gonna get the Complementary for the HV side of that for the native side In here So, right, so what we got then is Slap that down there. Okay It's pumping out quite well, but the highest we can go up with this now is 24.5 20 point there you go. Well, you get to see the highest we can go The fan doesn't die. It's like I said, it's got that buck converter and that regulates that down to 11 11.5 volts another simple circuit But you can get twice the power and use it variably on a little tiny transformer It's not gonna do a lot, but it's it's a worker. Cheers watching guys. Bye
