Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing.

[0038] figure 1 For background technology [Zhang D D, Zhou Y, Wang J, et al.A compact, high repetition-rate, nanosecond pulse generator based on magnetic pulse compression system [J]. IEEE Transactions on Dielectrics and Electrical Insulation, 2011,18(4):1151 -1157.】The circuit schematic diagram of the pulse modulator based on the two-stage SPT pulse compression unit still adopts the traditional winding structure. In order to obtain a large boost ratio, they use the two-stage SPT pulse compression unit for boosting. On the 307-1000Ω load, the output amplitude is 45-62kV, the pulse width is 70ns, and the high-voltage pulse of the leading edge is 30ns. The high-impedance load and the magnetic switch that plays a steepening role are the key to obtaining the fast leading edge pulse. Similarly, the existence of the steepening switch MS is not conducive to the solid state and comp...

Abstract

The invention relates to a microsecond pulse generator, particularly relates to an all-solid-state high-voltage microsecond pulse generator based on a FRSPT (Fractional-turn Ratio Saturable Pulse Transformer) and an anti-resonance network, and belongs to the field of pulse power. The pulse generator consists of a charging module, a pulse boosting module, a pulse forming module and a load. The charging module is mainly used for charging the pulse generator, and charges the pulse forming module by the pulse boosting module; the pulse boosting module is the FRSPT; in one aspect, the FRSPT is used as a transformer of the pulse boosting module, and in the other aspect, the FRSPT is used as a switch of the pulse forming module; and the pulse forming module is used for forming a quasi-square wave pulse which is reasonable in leading and lagging edge time and good in flat top degree. The pulse generator is long in service life and stable to operate; all-solid-state compact integration of the pulse generator is implemented; an output square wave is high in quality; and the all-solid-state high-voltage microsecond pulse generator can be used for the fields of a high-power microwave source, foods, sterilization and disinfection, wastewater treatment and the like.
