Gave it my best try but no go :P .... if it would of work there should be next to no change in DC current to the H-Bridge when I connect or disconnect the reactive circuit side of the Isolation transformer. But that was not the case. It went up when connected so I did the P/I & P/O power calculations of the increase and it was under unity.

I think I know what the problem is. Since the circuit is capacitive and current 90 degrees ahead of the voltage. I can see on the scope the current is crossing the zero line (going in the opposite direction of voltage) half way of through the voltage on time, so since the voltage is still on for the other half of the on time the current cannot go back to the source because the mosfet is maybe blocking itl. Do you understand?

Do you think it's possible to make an H-Bridge that could handle such a situation?

Thanks for your help Alex

Luc,

The attached circuit will probably suit the need for a solid state test circuit, for testing reactive power coupling.

Hi GL
Is this the circuit you will be trying?
I do have a few of those ferrite toroids.
Any idea as to why i couldnt get a phase shift in my posted circuit above?.Im thinking frequency is to low.

So i tried the pictured below,and simply changed the generator fo a MOT running of the main's.
No matter what cap/cap combination i used(1.2uf through to 200uf)i could not get the current/voltage phase to change??? The voltage/current phase would always remain the same as without the caps.However,the power draw went up on the input,and P/out went down at the same time.

Hi TinMan.

why would you do that test? when the circuit below is what I was saying to do?

Congratulations with your birthday and with your present Gotoluc!  ;D
You are one of a kind, wow.

@Luc

So a couple of questions.

1-why the need for a generator for the AC input?
2-What would be the difference in just useing grid AC supply?-pictured below

If no reflection is shown on the generator/motor when a load is applied,then the same should apply when grid conected.

Hi TinMan,

Good questions.

The reason I made a video demo using a Generator FIRST! ... is to eliminate the naysayers that this is just fooling the plug in Watt meter and basically steeling from the grid.
But if you hook it up to a Generator and it has no Lenz effect on it, then right away it eliminates that argument.
So feel free to use the grid and know that you are not stealing power from it.

After doing many tests you will come to realize that there is a benefit to raise the input voltage above 220vac and lowering the series input cap. This is why Valy's device has a 600vac Generator.

Cheers mate

Hi Oliver,

there is a country in this world who's ancient spiritual teachings are based on the correct way of life. There on ones birthday they give instead of expect.

Just though I would share

I tend to disagree about the power returned back when current and voltage are 90 degrees out of phase, or rather - I agree that happen in primary but not in secondary.

Hi forest,

I was talking of the Primary and not the secondary when explaining that.

Luc
For the very simple reason that my scope shares a common ground with the grid,and thus i cannot hook it to any part of the primary coil to measure current or voltage. So i went for an isolated setup.I simply replaced what would be your generator,with the MOT. So i dont see what the difference would be?.
The only way i could do it with a single transformer,is to use an inverter and 12 volt battery.This might actualy come in handy.

Okay, I see now

However, I don't think it will work that way as you are changing everything by adding another transformer.

Forget about your scope for now and just use the plug-in power meter as per my instructions.

Also, you should be able to use you scope without isolation if you make sure both your probe grounds are on the Neutral side of the grid.

Let me know if you get it working

Hi Tinman,

I did test my proposed circuit. Did use a 10uF capacitor for C1. The output
was disappointing low. I also saw that the input current usage did
go up when I connected a load. So back to the drawing board, LOL.

Is there an other -simplier ? -solution to stop and moderating the inrush current if not with an capacitor/condensator ?

Hello,

@Luc, one question:

What is the power dissipated at your 1 Kohm resistor ? Your Power-meter will not give you the correct value, because it measures the power in the whole system. May be I just missed it while watching your vid, but you need to measure voltage and current directly at your resistor ( must be in-phase) or you
measure the temperature and use a dc-supply heating up the very same resistor to the same temperature and register voltage and current on your dc-supply.
What I understand : you have achieved a reduction in power-loss in all parts of the system together but this does not mean you have less rms-power than the one dissipating at the 1 Kohm-resistor which is about 3.5 Watt.
Rotoverter-technique published by Hector does the same thing according to my understanding

You are showing oscilloscope-curves just explaining : Here are voltage and current curves .. but I miss the one across the load-resistor.
What is the exact frequency and the signal-form across this 1 Kohm-resistor ? Are there build-in rectifier-diodes ? We then would have 120 Hz pulses filtered through the cap into primary of the mot.

And of course you are using 50 Watt rms AND X Watt ??? reactive power from the grid. Power companies also have calculated factors in their prices for reactive power because any driver-motors of houshold-devices ( fridge, washing-machine etc) have a certain amount of reactive power. This is the reason why very big
industrial customers need to take care of reactive-power-compensation in their machines since reactive power also needs energy to be supplied to pump the power into the net and back to the generator again

@tinman: Concerning the  pic "First Test Setup"

You have three lines at your wall-socket. A hot wire, a neutral wire and a ground-wire. If you connect the ground-wire to the neutral wire and your automatic fuse

does not react because of high loop-currents, you can then connect  the Ground-Clip of your scope to the neutral-ground-wire-connection. But first you need to

find out the hot-wire.
How to do this: Connect one probe of your multimeter to the ground-wire and find with the other probe the wire which gives you a 120 V ac reading. Measure then the other wire- it must give you a zero-reading = neutral wire.
Then change  the switch of your mulitmeter to ac-current-mode ( > 1 A ) and connect the meter between neutral- and ground- wire. This will show you the loop-current. Change to 200 mA if your first reading indicates that you are below 200 mA

dancombine shows here in his transverter-tests the problems of extracting real power from an resonating LC-Tank.
Up to now they have not solved the problem:

Hi GL

do you have a plug-in meter and a Mot?

If so, can you do the simple (attached to grid) test I propose and report your results.

From there you may have a better idea of what would need to be done for a solid state version.

That way you will find your MOT's ideal cap and load resistor (for 50Hz) which should be easier for testing an input of a 50Hz from a solid state switch

Does that make sense?

Thanks

Luc

Luc,

Yes it makes sense. But I will not mess around with the mains. We do not have the same mains
over here as you do. I also do not have any MOT or enough non-polarized capacitors to play with.
I'm hope it can be done with solid state because 12VDC is my preferred voltage to play with.
