A repetitive pulsed magnetic fields serving as the guiding magnetic field for the repetitive high-power microwave source has been proposed, which makes the source compact with low loss and small heat. A primary energy source for solenoid which can output rep-rate pulsing magnetic field is developed. It adopts half-bridge topology with series resonant constant-current charging technology and the output is adjustable, from 0 to 2.5 kW. The average power can reach 5 kW at most. Without adding other resonant components, the circuit makes full use of the transformer leakage inductance and bridge-arm capacitance so as to reduce the influences of the transformer parameter. The operating process of the circuit is analyzed briefly. The parameters of the power supply are calculated and a designed example is presented. The emulation and experiments are given and experimental results are in accordance with the calculation request. The primary energy source is experimentally investigated across a solenoid and it can work steady at 10 Hz rep-mode.
