Abstract:

The micro texture of the surface was studied by the mask electrolysis process. A high frequency and high voltage pulse power supply was designed for the special process.In this paper, the characteristics of the switching device are analyzed, and the working frequency and waveform distortion are deduced by considering the power, switching speed and other factors. IGBT is used as the switching device, and the three-phase AC bridge rectifier circuit is used to convert the AC current into a smooth DC current.In the Matlab/SimPowerSystems environment, the power model is built and simulated. The simulation results show that the experimental waveform of each node is in line with expectations.
