Sharping Circuit Of Plasma Pulse Power Topology And The Simulation Research

The application of plasma has a vast prospect on industry and military. Plasma generator is the main supply of plasma equipment. But a power supply that is able to generate fast rise time and high repetition rate pulses is needed for plasma generators,excimer laser and laser beam weapons.This domestic and foreign literature in a wide range of reading and in-depth study of existing technology based on switch power supply, with the switching power supply for the plasma study, the pressure regulator from the power circuit topology structure, regulator circuit output voltage ripple and pulse steep of technology, Circuit-related technology, the system carried out to explore and study the following:Firstly, plasma switching power supply regulator circuit is good or bad performance of its power the key to the topological structure of the power supply will directly affect performance. Therefore, the power regulator circuit topology to optimize the design to conform to technical requirements of power is one of the key issues of this article. In the systematic analysis of plasma of various switching power supply regulator circuit topology of the working principle and process, based on analysis and comparison of the advantages and disadvantages of the various topologies and application environment, and gives all the typical application circuit converter.Secondly, in circuit switching power supply topology based on the analysis, simulation model was constructed step-up converter, and simulation studies are given under the influence of three modes of high-frequency PWM control of high voltage switching power supply regulator circuit output voltage ripple factor various factors, for the design of plasma generator switching power supply provides a reference.Finally, pulse compression circuit is a steep gradient of plasma pressure generated by the primary power supply voltage of steep high-frequency sine important means of dealing with its steep processing a direct impact on the quality of the plasma generator power supply is good or bad, due to the steep gradient pulse compression.There are many ways the design of the circuit for the election side, it is essential to their selection and simulation. Based on the analysis of the magnetic switch and working principle of the magnetic pulse compression characteristics of the network, and the important characteristics of magnetic switch model based on the pulse sharping circuit design method, and the pulse sharping circuit design is simulated, and the results proved the theoretical analysis and design method is effective.Meanwhile, the steep gradient of the compression circuit input and output characteristics of the various parts of the system of testing to do research and analysis, given the test data and waveforms; on the simulation results and experimental results are analyzed and compared to find out the operating rules of the circuit.The research method, this thesis first modeling analysis, then the computer simulation, circuit simulation model built after the trinity of strategy. In thesis, the main circuit structure of a large number of simulation analysis, such as voltage regulation converter, magnetic switch core model, the steep gradient compression system circuit, thereby reducing research costs, faster, higher and better results of scientific research.
