Hi,
I am trying to design a RLC discharge circuit such that 2 paralleled capacitors are connected to a coaxial pulse transformer, which in turn, is connected to a RL load. To ensure that the maximum energy is discharged into the RL load, the pulse transformer's primary resistance is matched to the equivalent capacitors' ESR. The pulse transformer is supposed to amp up the current pulsed through the RL load.
After running a simulation, I noticed 4 problems that I can't solve:-
1. the charge voltage of the capacitor is 360V, but yet when I simulate the voltage of the capacitors, I get this:
2. the current in the secondary winding should be larger than that in the primary, but the simulation shows otherwise:
3. the secondary current doesn't terminate at 0 long after the pulse whereas the primary current does
4. the integration of instantaneous power across the primary winding shows that only 35.86 J is supplied to the primary winding (vs. initial capacitive energy = 388.8 J), which suggests very high impedance mismatch
Individual component parasitics were included into this circuit. However, even if the pulse transformer's parasitics were to be removed, the same 4 problems persist. Could anyone please tell me what I am not doing right?
I have attached the schematic for your reference and thank you for taking the time to read this.
