Abstract: The primary magnetic field coil (PMFC) power supply system is designed for pumping the PMFC of the kilo-tesla cylindrical implosion magnetic flux compression generator (MC-1) to produce initial magnetic field. It is the key equipment of the MC-1 system. Based on analysis of the requirements and the key techniques, the key components, pulsed forming circuits and control system of the PMFC power supply system were designed. The power supply system with the output voltage adjustable from 1 kV to 40 kV, the rise front about 60 μs and the peak current reached 3.2 MA was developed successfully. The power supply system has been applied to the dynamic test of the kilo-tesla cylindrical implosion magnetic flux compression (MC-1) generator.
