Inductance energy storage type pulse power supply used for electromagnetic emission

Abstract

The invention relates to an inductance energy storage type pulse power supply used for electromagnetic emission, which belongs to the technical field of electromagnetic emission and comprises a primary power supply, a first feedback energy thyristor, a second feedback energy thyristor, a plurality of power supply side thyristors, a plurality of inductance energy storage pulse units and a load thyristor. The pulse power supply has extremely strong current amplification capability and is capable of expanding a system by improving current level of the primary power supply and increasing the grade of the inductance energy storage pulse units. The power supply adopts the thyristors and low coupling inductors, utilizes an auxiliary circuit for current exchange, and is capable of greatly reducing equipment cost. The adopted low coupling inductors can lowers requirements for the inductor manufacture process. An energy feedback mechanism is introduced, and system energy utilization ratio can reach high as 70%. The power supply can achieve any wanted current waveform, thereby being suitable for electromagnetic emission.

Description

technical field [0001] The invention relates to an inductive energy storage type pulse power supply for electromagnetic emission, belonging to the technical field of electromagnetic emission. Background technique [0002] The research on electromagnetic emission has a history of more than one hundred years. With the intensification of energy crisis and the development of power technology and control technology, electromagnetic emission technology has received more and more attention, especially the development of computer technology and power electronics technology. Further development has accelerated the process of electromagnetic emission technology moving towards practicality. [0003] The pulse power supply system can generally be divided into three parts: primary power supply, intermediate energy storage and pulse forming system, and conversion system. Due to the low power density of the primary power supply, it cannot meet the requirements of electromagnetic emission,...

IAT is currently researching the implementation of GTO, but there is still no actual progress

[0016] 2. In order to obtain a large load current multiplication factor, STRETCH meat grinder uses a high coupling inductance, requiring a coupling coefficient as high as 0.94 (at this time, the current multiplication factor can be close to 10), which brings great difficulties in the process and extremely high cost

[0018] Neither of the above two mainstream topologies introduces an energy feedback mechanism. After the load is launched, the magnetic field energy in the inductor can only be released through an external resistor, and the energy utilization efficiency of both is lower than 50%.
