Generate 220v AC from 12v 64 Amps Car Alternator via Solar Panel Excitation ( 21 volts )
Hi, guys, hey what you see is a 12-volt scar, altering it. Oh, you can see that at the back of it there is no three-phase rectifier, because I took it out since I converted this into a three-phase brushless DC motor.
Now guys, a car alternator produces 12 volts at an RPM of around 2,000 or more, and my target is to produce 12 volts at 3 times less than rated RPM, which is somewhere around 700 RPM. So guys. These four are the wires coming out from the armature winding.
Now among these full. There is one tapping point because it is a star connected finding, since this terminal is the thicker one. So the probability is high for the tapping point to be this one. So let’s, remove it so guys.
Here you can see the tapping point. The remaining three are normal: all the wires are coming on and joining at this point. So what I have to do is D solder it and remove the tapping. Now guys are the armature winding of this alternative contains three separate windings.
Now you see here six wires, okay, one two, three, the smaller one, four, five and six. Now these six wires are from three coils : so guys it’s time to replace the brushes back at the back of this alternate again: .
Okay, so guys now the wiring has been done and also space has been created for installing the new wires. Let’s, install it so guys to connect the pressures back again. All you have to do is push them inside and keep them held back with a metal or thin metal piece or oil pen.
Okay, so one is already in, as you can see, the other one is held back okay, so guys. The case has been installed as before. Now I have to remove this metal wire to make the brush get in contact with the slip ring.
Okay, so now it’s in contact. Okay, so guys are. The old leader is all set for testing so the phase virus will be connected in series to increase the overall armature winding voltage power phase.
So three phases will be connected in series so guys here, as you can see that I’m using a UPS battery 12 volts, a 70-inch chloride. So I’ve connected the terminals from the UPS battery to the brush slip ring terminals, a red and blue.
Although one wire is not connected that, I will connect afterwards and the wires from the alternator have been connected in series and the final output is appearing on this green wire and this black wire.
So here what I have as multimeter, pointing towards 200 volts AC mode to measure the generated voltage from the alternator. So let’s. Do the connections and do the test? Ok black to black, although it does not matters because the old is coming out from the alternator is going to be AC, so polarity does not matters at the moment, so the wires have been connected.
Meter is pointing towards with zero point, zero volts and one wire from the ligase battery has been connected to the brushes. Now let’s, connect the other wire to and then move the shaft to see some generated voltage and after that I’m, going to do some rope rotation, so zero rules, so maximum that I did was three volts with hand rotation.
Okay, the thread has been found now I have to touch the terminal to the battery. Ok, the connection has been made, keep watching the screen whoa so guys, as you saw, that I generated around 14 volts AC with the help of this alternator with simple rope rotation, which is really awesome, which means that the series connection, the modification that I did are Actually, working a little higher rpm somewhere around 2000 AD, it is going to produce 36 volts so guys this is the Royal Enfield headlamp bird that I am going to use to connect her to this ordering it out and test its power connecting this fire.
Okay, go! Okay, so guys this is a single phase. Rectifier 35 amperes, which I’m, going to connect. So, as you can see here, the plus positive terminal – and this is the AC – the black and red – are the AC.
If this one is AC, then the diagonal opposite is also AC, so these two will be connected to the black and green terminal from the alternate. Oh one is done, comes the second one. That also is done now.
Finally, the output will be DC and will appear on blue and black, so let’s, connect ammeter again so guys, as you can see, I have connected the rectifier and the terminals of the meter, and now it is pointing towards 20 volts DC mode.
Although this brush brushes and the rotor system has not been excited, I will connect the wires, so I found the threat now it’s time to connect in the blue terminal, the rotor winding, okay, that being done watch the meter screen.
So it was 11 point 5 volts DC a little bit voltage went because of the forward biasing around of 1 point 4 volts and now guys, since the output is DC. Okay, I can also measure the output current, since I have seen the winding connections.
Let’s, see the impact of that okay watch. The screen around 5.8 1 amperes is what I produced by the Rope rotation test. So the total power that I produced was around 72 watts, so guys here, what you see are three rectifiers 35 ampere single-phase, which will be connected to the output terminals of the alternator.
This is a thirty-eight watts solar panel. Now I’m, going to measure its voltage. You can see. I have pointed out at the meter towards 200 volts DC mode because its voltage is going to be more than 20 as you can see it’s.
Twenty point, one volts. Now measuring its current and this panel is very old, almost eight to nine years old and you can see it as still producing one point: five amperes DC. Now this is a sixty Watts.
12 volts car headlamp bulb 60 watts, meaning that it will take somewhere around five amperes from a DC source. So I have connected the solar panel output terminals and, as you can see, that it is not glowing because obviously the current from the solar panel is not high enough.
Now the three rectifiers are here on which the base I will keep the Weiss and otherwise is for mounting the alternator and the three-phase virus. Independent windings will be connected to the three independent rectifiers and the output of the rectifier will be connected in series to increase the voltage at the same rpm three times.
The final output will appear on this blue and a red terminal red being positive and blue. Being the negative terminal you can see, the brush terminals are still not connected red and blue. These two wires will be connected to the output from the solar panel, which this video is about.
So let’s connect the output of the rectifier to the multimeter in 20, volts DC mode to measure the voltage being generated by the alternate after its excitation with the solar panel. So the solar panel wires have been connected to the brush or rotor terminals of the alternator, and the alternate errata winding is excited.
Now now let’s, mount the thread and measure the generated voltage with the help of the multimeter and, as you can see, the generated voltage was nine point. Two two volts: let’s, try once again a little harder and, as you can see, the voltage has increased by ten point, two five volts DC.
Now, since the output from the rectifier is direct current, so I can also measure the current in ampere mode. Okay, keep watching the display screen and, as you can see, the current was as high as seven point: five seven amperes once again yeah this time.
It was not that high five point one eight amps now I’m, going to extend the final output wires from the rectifier set and connect a sixty watts, car headlamp, bulb and try. If this setup can glow this ball, sixty watts – and initially you saw that this bulb did not glow from the output terminals of the solar panel.
Let’s, see if this way it glows and as you can see that it is slowing. You might see that it is glowing really dim, but it is very bright and it’s 12:00 at the noon. So, for that reason, even though it has grow, it is growing a really bright and still you cannot see it because it’s very bright in the Sun.
Now this is a 12 volts to 220 volts. A UPS transformer that I’m, going to use to step up the output wire to step up the output voltage from the alternator the generated voltage. You can see the windings have been connected in series.
Let’s connect again. The solar panel terminals to the brush terminals and at the final output will be connected to the rectifier you can see here. The weather is very cloudy, so I have to wait for the Sun for better excitation of the rotor winding.
At present, there is no Sun. Now it is, and you can see that the voltage generated was fourteen point two volts again no Sun and I’m going to try to glow the bulb. You can see the bulb isn’t glowing because the solar panel isn’t feeding the rotor winding enough, and now it is glowing because now the output from the solar panel is good enough for 100 watts bulb to glow.
So guys. Now what I am going to do is excite the rotor or field winding with a 7h UPS battery and step up the armature overall output voltage with the help of a 220 volts UPS transformer and to the output terminals.
I am going to connect a multimeter pointing towards 750 volts easy. I’m, going to follow the same procedure of winding the thread and connecting the two terminals of the brushes to the battery. Windings excited watch the screen and you can see the generated voltage is somewhere around 234 volts.
Here you can see 272 volts on the second try. Now I’m going to try the same 100 watts bulb inside the room, not in the Sun. It’s, a 220 volts 400 watts, usual incandescent bulb terminals have been connected to the UPS.
Output. Winding has been excited, keep watching the bulb and, as you can see, it is flowing bright. Let’s, turn off the lights and try again, and you can see that it is much brighter now cool. So I’m, removing the bulb.
I’m, connecting a simple 9 watts LED bulb. It is glowing really bright and also it is not hard enough for me to blow the bulb by rotating the alternator. This is a 200 Watts led halogen that I’m, going to try and glow.
If this alternator can handle this big load so everywhere has been connected. Okay, you can see that it is easily glowing to full potential the LED halogen lights – very nice. Okay, so guys that would be all about today’s.
