Hi Sven,

The current is continuous according to the mathematics and to my experience. That's principle used to design flyback pulses and they reach the voltage designed for by using the formulas describing that phenomena.

Circuit simulators also use the formulas to bring up the solution which has to fit the practical experiment. Of course this involves making the correct models of the components including their different parasitic (not intended) parameters. Else a circuit simulator is of no practical use.

 Hello Ole,
 
 are you sure the current continues to flow primarily through the inductor, he could still do extra work after the inductor.
 
 I think there is something else. I would like to see the one who makes the inductor cool and freeze at work.
 I have already seen pictures of it. But that would be the thermal path from heat to electrical energy.
 Maybe just a dream.

   Hi Sven,
 
 "A flyback converter uses only the stored energy in the magnetic field, the energy used to build up the magnetic field disappears as a loss. Maybe I think that's too easy."
 First energy is stored in the inductor (input cycle) and then it is transferred to the output load (output cycle). The load then dissipates or converts the energy into another form. As long as a current flows it has movement and a magnetic field surrounding it. Decreasing the current decreases the magnetic field of the current. How fast the current is changed determines the voltage that is induced. Or how fast the voltage is changed determines the current that it drives. This is if the inductor has only pure inductance. A real inductor also has resistance and capacitance which also affects the result.

 Ole

   Hello Ole,
 
 I try again with simple words to give it back.
 I think the magnetic energy adds to the added energy. Practically, we only use one kind of energy at a time.

 When I read through the relevant Pdfs by Hector or Dan Combine, it sounds like a dream of the future.
 
 I will try to tune in the 1200W spotlights today and see if this happens at power factor 0.
 I can measure the current across the shunt and see the shift. If that succeeds at power factor 0 and the lights are on, there is usable energy in it.

Hi Sven,

When the negative side is different from the positive side perhaps the circuit isn't symmetric. This includes either the triggering circuit or the source of the voltage.

You could test if the Ferro resonant transformer gives off more energy than it requires running it. That would be a prerequisite for getting free energy. But that requires making power measurements or energy measurements which is hard to do without the proper equipment.

Regards
Ole

 I try again to make all components the same as possible or adapt.
 
 I always have better performance with negative diode plugs, no matter how I change the polarity or the capacitors. The average power and peak is always much higher there, sometimes 15 to 20 volts, so I do not get natural synchronicity with the main LC.

Hi Sven,

"could you make improvements to the phase control, you have my drawings yes."
I think a peak triggering circuit would be right to use. At least this would be useful if the capacitors are to be discharged at their peak level. Peak level means that they don't receive any more charge or that the current stops charging them. If discharging before that moment the charging current is also connected to the load that discharges the capacitors.

The impedance for a full discharge in max a half cycle can also be calculated. Or the max voltage for a full discharge into some given impedance in max a half cycle can be calculated.

The circuit you're using is a variable phase controller. It doesn't prevent firing before the capacitors are fully charged. The voltage could be phase shifted 90 degrees and then triggering could be done by using a zero voltage detector. Else the current could be monitored and then triggering when the current declines to zero.

Regards
Ole

 I have taken over from jöretronik, but then with potentiometers at R2 and P used.
 
 I have now seen circuits where a potentiometer is connected directly to the trigger capacitor or with resistor, one has advantages?
 
 Maybe it's just because of my Thyristorzündung that the thyristor can not ignite later.

Hi Sven,

The circuits in the links are just variable phase controllers. They won't detect when the peak is reached.

Perhaps another way would be to monitor the charging voltage or current and find all the zero crossings. The trigger signal could then be filtered by some logic gates that triggers each time the capacitors would be max charged in each cycle. This would trig no matter the amount of charge the capacitors actually receive.

Regards
Ole

 Hi Ole,
 
 I again, this topic with the ignition does not let me go.
 I have found a pdf here and this circuit, what do you think of it is there still room for improvement for my diode plug igniter?

SvenWhat I did with the RV is replicate an idea of one of our group who we haven't heard from for quite a while, Dmitri..I powered the RV motor using a 12 V DC 150 Watt inverter delivering 60 hz Ac

Hello to all interested,

I can not get on with the diode plug and have just connected a FWBR s.der coupling capacitors and sometimes played with different loads and just times with the scope measured at various measuring points as the SCR stops working.

I noticed that actually every diode plug must be charged twice before it triggers to think I work as Hector says. I hope he rectifies me.

I've always wondered why he always thought to unload 30x SCR Minus and unload 30x SCR plus. There is a sine wave of 2 half-waves, if it is discharged each time, the value at 60Hz would be twice as high.

I hope this message comes over otherwise I give it up.

regards

Sven
