摘　　要：通过掩膜电解加工方法对生物表面微织构进行研究,针对特殊工艺的需要,设计了一种高频高压脉冲电源;分析了开关器件的特点,在综合考虑功率、开关速度等因素情况下,对工作频率及波形失真进行了推导;采用IGBT作为开关器件,利用三相桥式全控整流电路,把工频交流电整形为波动平滑的直流电;在Matlab/SimPowerSystems环境中构建了电源模型并进行了仿真,仿真结果表明,各节点的实验波形符合预期。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.
