| description | The static (unloaded) electrical parameters of a capacitor bank are of utmost importance for the
purpose of modeling the system as a whole when the capacitor bank is discharged into its dynamic
electromagnetic load. Using a physical short circuit across the electromagnetic load is usually
technically difficult and is unnecessary. The discharge can be operated at the highest pressure
permissible in order to minimize current sheet motion, thus simulating zero dynamic load, to enable
bank parameters, static inductance L0, and resistance r0 to be obtained using lightly damped sinusoid
equations given the bank capacitance C0. However, for a plasma focus, even at the highest
permissible pressure it is found that there is significant residual motion, so that the assumption of a
zero dynamic load introduces unacceptable errors into the determination of the circuit parameters.
To overcome this problem, the Lee model code is used to fit the computed current trace to the
measured current waveform. Hence the dynamics is incorporated into the solution and the capacitor
bank parameters are computed using the Lee model code, and more accurate static bank parameters
are obtained. |
