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?
 
 regards

 Hello Ole,
 
 could you make improvements to the phase control, you have my drawings yes.
 
 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.
 
 regards
 
 Sven

 Hi Ole,
 
 I said what else could I test on the transverter to get positive results or adjust.
 
 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,
 
 "Do you have any idea what I could try?"
 I lost you here. Idea to peak detector or stable output or what?

 Ole

   Hi Ole,
 
 I do not understand that completely, finally we have an alternating field and the polarity is constantly changing.
