Each first follow current loop comprises a first resistor and a first one-way conducting element, wherein the first resistor and the first one-way conducting element are sequentially connected to the two ends of the first capacitor. Each second follow current loop comprises a second resistor and a second one-way conducting element, wherein the second resistor and the second one-way conducting element are sequentially connected to the two ends of the second capacitor. Flat-topped currents / magnetic fields can be generated through the coupling effect of the primary side coils and the secondary side coils of the transformer, and the flat-topped pulse magnetic field generating device and the flat-topped pulse current generating device have the advantages that manufacturing cost is low, the process is simple, circuit control is convenient and quick, and the flat-topped currents / magnetic fields do not have ripple waves.

Description

technical field [0001] The invention belongs to the field of strong magnetic field technology, and more specifically relates to a flat-top pulse magnetic field generating device and a flat-top pulse current generating device. Background technique [0002] The rail-type electromagnetic drive system has become a hot spot in the field of electromagnetic emission. During the working process of the rail-type electromagnetic drive system using a solid armature, the sliding performance of the solid armature is related to its own structural shape, size, and material properties. The output waveform of the current is related. In order to enable the solid armature to withstand higher charge and discharge energy and achieve a higher exit velocity, the output pulse current should be modulated as much as possible according to the flat-top principle in electromagnetic emission. At the same time, the flat top current is also conducive to good contact between the solid armature and the guid...
