Energy input by square wave + -170VDC, with component’s parameter as in schematic

Parameters to be recorded: V; I; Pat positions L1, L2, R2; R3
R2 AC resistance of L2
R3+C4 simulate resistor of the spark (I’ve saw somewhere on internet)
Preliminary parameters:

Primary current (image1) 400Apkmax
Output voltage (image2)180KVmax
Internal dissipation in L2 (R2) (image3) 8Kwmax
Spark power dissipation (image4) 58Kwmax
L1 Total power=reactance power dissipation power(image5) 510KVAmax
L2  Total power=reactance power dissipation power(image6) 290kVAmax
Preliminary comment:
*Voltage gain factor √(L2/L1)=100
It works looks good with this parameter
*Compare with SGTC, DRSSTC working stronger and longer spark because several cycle of electricity pump continuously in to L1 (according to demand)
 In SGTC only halt cycle by C1 discharge in to L1 is all the power in for every bang.
*I am not sure R2=100k and C4=5p simulate exactly the real spark is difficult to measure.
*DRSSTC can run in 2 modes: primary feedback and secondary feedback running frequency and performance will different some. (Primary feedback is better)
*Hard to determine exactly the resonance frequency that the coils run so the frequency at the input while simulating better when we make practice and simulating together at the same time.
