The system according to claim 1, wherein the at least one additional shaft current pulse is independently controlled from the formation power pulse. 3. The system of claim 2, wherein the controller is configured to provide the at least one additional shaft current pulse at a pre-determined time. 4. The system of claim 3, wherein a profile shape of the at least one additional shaft current pulse is configured to provide an increase of the plasma toroidal field that matches an increase of the plasma poloidal field during the plasma compression time. 5. The system of claim 1, wherein the at least one additional shaft current pulse comprises at least two additional shaft current pulses during the plasma compression time. 6. The system of claim 5, wherein a timing table for the shaft current pulses is provided to the controller so that the at least two additional shaft current pulses are pre-set based on a trigger time of the plasma compression driver and a compression trajectory. 7. The system according to claim 2, further comprising a plurality of probes to measure parameters of the plasma in the plasma generator and the flux conserver, the plurality of probes being in communication with the controller to provide an input signal to the controller, the controller processing the input signal and adjusting an output signal to the shaft power circuit to adjust the at least one additional shaft current pulse. 8. The system according to claim 7, wherein the controller triggers the shaft power circuit to increase shaft power pulse when increase of plasma poloidal field is detected. 9. The system of claim 1, wherein the at least one additional shaft current pulse is triggered before triggering of the plasma compression driver.
