Hi My Honorable Mr. Swagatam,
I am Dare by name.
Thank you so much for your kindness in using your Concentrated wealth of experience in Electronic Engineering to help humanity the way you are doing.
I came across your website when searching for on Google, alternator booster which helps small Genset of 650W to bear load more than there capacity.
Please, I need your assistance.
I want to build an over unity electric power generator of 12VDC output by using 1 DC motor generator that is said to generate up to 150V/2A at 3000RPM and One DC Motor.
One of the Motors will be driving the other while the other one will be generating the voltage as it is being driven by the other as seen below.
Now in the diagram above Sir, once the switch (9) is on, the part I numbered 1 (motor) will be driving the part I numbered 2 (generator).
The generator will be generating high voltage and sending it to part numbered 3 which is an integrated DC to DC step down and Step-Up Power Circuit and load bearer.
The Power Circuit would step-down the incoming upward of 100VDC to 12VDC or 24VDC but step-up the Amps from the incoming less than 2A to upward of 30A.
So assuming the final output voltage is 12V/30A then it will further it to the part labeled 4 which is the Inverter. The inverter will both supply the house and simultaneously supply the AC to DC transformer which I numbered 5. The AC to DC will convert the incoming voltage of 220VAC or 120VAC to 24VDC.
The 24VDC from the transformer will enter the part numbered 7a. The part numbered 7a will supply voltage to the part numbered 7b which is the battery.
The Battery which will be Lithium Polymer battery of 22.2V (Six 3.7V batteries connected in Series) will be getting constantly charged by 24VDC from the Circuit Panel numbered 7a. While at the same time be getting discharged at 10VDC/5A through 7a.
Furthermore the part I numbered 7a will function as, Battery over charge protector, over discharge protector, and continuous further power supply to the part I numbered 6 which again is the Voltage Booster that will be receiving 10VDC/5A from 7ab and Step it up to 24VDC which will further be supplied to the Driving Motor which is numbered 1 in the diagram above.
The Battery function is to act as a standby power on for the generator.
The intermediate switch which I numbered 9 between the protected battery and the Motor or Driver is the bridge. It allows for switching on and off the Generator when one wish.
From the Driving Motor, the cycle begins again.
Now, I please need your guidance as follows:
1: Will it be better to use a DC Generator that can generate directly lesser
Voltage but Higher amps (e.g 35V/15A)??
Ans: A DC generator will work better, as these are designed specifically for generating electricity.
2. What kind of Motor and Generator will work best? Permanent Magnet Brushed or Permanent Magnet Brushless?
Ans: Permanent Magnet brushless type is recommended.
3. In my design above, the inverter will not be receiving input voltage from a battery but instead from the earlier mentioned integrated DC to DC step down and Step-Up Power Circuit and load bearer (600W). Is this possible?
Ans: Yes the inverter will work equally well with it as long as the input is well filtered into a clean DC.
4. Does an inverter act as load too? If yes, how do I calculate the load of an inverter that is rated 500W load bearer or 500W output power? I mean if an inverter can bear a load of say 500W, what will be the load that such inverter will mount on any device that generates DC voltage of 12VDC or 24VDC.
Ans: Inverter will not act as a load but will surely introduce some losses, may be 10% or 20% depending on the quality or the topology used
5. What is the general minimum and maximum required Amp of an inverter before it can work? Will an Inverter works even if it receives say 12VDC/2A or 24VDC/2A input power?
Ans: Yes, the minimum amp will be actually the minimum amp at which the devices turn ON which may be in milliamps, so this issue can be negligible and can be ignored.
6. In my own layman knowledge, I think constantly charging the battery of 22.2VDC/2.6A with 24VDC and discharging it to 10V/5A will not make the battery run-out of power. May I know if this is correct?
Ans: Charging it with 24 V is OK, but discharging it to 10 V will surely damage the battery very soon
7. If not, please how can I make sure the battery does not run out of power and thereby cause the system to stop working at any time it is switch on?
Ans: Do not allow the battery to discharge below 21 V
8. Is it possible to use Super Capacitor in place of the batteries as they will be getting charged quicker more than the battery?
Ans: Yes it may be tried along with the Lipo battery, alone these may not be so effective
I Hope to receive your reply soonest.
Warning: The above concept looks fascinating but practically it will never work.
