Hello Douglas, I have to trigger the scrs shortly after the peak so reactively no more current flows, I think, so it is really non-reflected. Now I manage just before the peak trigger 1/4 of the sine to charge and 1/4 to discharge better a little later 4/12 to charge and 2/12 to discharge. Unloading is not a problem as I can adapt the load to the impedance via a Variac. The ignition after the peak is the problem, I wanted to install a coil in the ignition circuit as an energy supplier, I unfortunately forgot a blocking diode in my first tests perhaps the only problem. I hope the translation is understandable. Greetings Sven

      Hi Sven

If using SCRs to switch diode plug ( I think at least) that there must be zero voltage in cap before the SCR will switch and so this means there must be  emptied-completely caps after discharge in the diode plug....is this correct?

If so, now it's much.more difficult to re-fill.the empty cap for next cycle as compared to a half-full cap for example.

Also creates problems where in the 1/4 wave exactly things will trigger too.

Try paralleled mosfets perhaps, and trigger with Ron Pugh's sinewave peak sensing circuit...use MOT as signal source and  power source too for it...pretty simple very accurate connect to mosfet driver chip imput....pulse width one chip using pot, where in sinewave adjust using another pot....third chip is chopper you can bypass by connectingosfet driver to J1 in circuit.

Paralell MOT HV side to AC you want to switch

The high impedance will affect nothing so use low voltage side of MOTs as signal amd.power for this circuit below...use scope when adjusting timing..

Here is circuit it works great:
