Hi Sven,

"Of course I have to split the lines through the capacitor bank with the switches so that I can switch several capacitors in parallel. Can the switch contacts of the switches cause this difference. Or is it due to the cable length at the transverter. I have these differences without diode plug or other observed and measured."
I've been looking for your schematic. If it's still like this pasted one the positive and negative sides don't trig at the same voltage. To be able to do that the triggering circuits of each side have to see the same potential. The tolerances of the capacitors can also be the problem. If switching place of the capacitors also shifts the asymmetry it is because the capacitors aren't of the same value.

The left hand side has the filter resistor go to the anode of the thyristor. The right hand side has its filter resistor go to the opposite pole of the main capacitor and thus only see the voltage across that capacitor. The left side ought to be coupled that same way for symmetry. I.e. move the 1k resistor to the other side of the primary winding to connect the triggering input directly across the left side 15uF capacitor.

 Hi Ole,

that is not so much, the incandescent lamp with 116 watts light up slightly with a 400 watts load on the secondary side, at 1200 watts load with a 3x 400 watt incandescent bulbs the 116W incandescent light only slightly, so you can once again shorten the switching times minimal perhaps If necessary, install a small capacitor and the light bulb parallel to it. It is signaled anyway how the impedance behaves, a great indicator. The thyristors switch off really fast, the actual 5 milli seconds I have to unload is not nearly needed. I think that with me the synchrony of the components and the length of the lines is a problem.

I recently connected the rotating iron meters for electricity differently or took the other line to the capacitor bank and measured slightly less current there than in the other current path.

The problem of how should I change that apparently does not flow everywhere at the reactive power the same electrical currents.

Of course I have to split the lines through the capacitor bank with the switches so that I can switch several capacitors in parallel. Can the switch contacts of the switches cause this difference. Or is it due to the cable length at the transverter. I have these differences without diode plug or other observed and measured.
