Research On Pulsed Magnetic Field Measurement Technology Of Modular Power Supply

This dissertation is based on electromagnetic launch technology, and introduced detailed about the pulsed power technology which is very important in electromagnetic launch technology. During the development of the electromagnetic launch technology, the higher demand is asked to the module of pulsed power supply. In the process of development, how to reduce the influence by pulsed magnetic field which caused by module discharge is become a very important problem. The main content of this dissertation is measurement technology research of the pulsed magnetic field. The major work is as follows:First, introduce some basic theory of the electromagnetic field , such as the setting of conditions, the boundary conditions and the calculation of the electromagnetic field theory analytical method, in accordance with the various components within the module to the characteristics of choice within the reactor modules for the analysis, based on a pulsed reactor coil Model to calculate the pulse reactor at different locations outside the axial magnetic field pulse of the size.Secondly, analysis the basic characteristics of the magnetic field, introduce testing method and the basic principles of magnetic field, then under this test environment and the actual conditions. Choose Hall effect method and the effect of electromagnetic induction method for measurement.Then, use different way to measure the amplitude and waveform of pulsed magnetic field in the three test points within the pulsed power supply module, during the measurement, change the charging voltage and finally do the data processing.Finally, compare the various points on the test using a different method of testing data results, focus on the signal in the formation of a falling edge reasons, the two methods were compared and analyzed about the advantages and disadvantages, and make suggestions about the deficiencies and shortcomings at last.Through this dissertation, a research has been made on the pulsed magnetic field measurement technology, which has a good guidance on the design of pulsed power supply module.
