Meat Grinder With ACC Circuit: A Novel Circuit for Inductive Pulsed Power Supplies

The inductive pulse power supplies attract researchers' attention as an important part of the electromagnetic launch system. However, in each topology of the meat grinder class circuits, the precharging of the auxiliary capacitor may cause many problems: the time-consuming precharging severely limits the repetition operating frequency, the charging devices and charging ports increase the complexity of the system, and there is a short-circuit safety hazard in actual operation. In order to solve the above problems, the meat grinder with an auto-charged commutating capacitor (ACC) circuit is proposed, in which the auto-charging of auxiliary capacitor is realized through topology design. Its working process is analyzed stage by stage, and the experiment of this circuit with 43 kJ is carried out. The experimental results are well fit with the simulation waveform, and the repeated operation is realized without precharging.
