【摘要】 文章用解析的方法对电容滤波型三相桥式整流电路的输出电压做了较深入的分析。在分析中考虑了该整流电路网侧电流连续的特点,同时也考虑了网侧阻抗的影响,并由不同的电路模型推导出输出整流电压的解析式。最后由仿真验证了理论结果,该方法为NBI加速极高压电源及此类大功率整流电路的设计提供了可靠的依据。更多还原

【Abstract】 For the power supply of the accelerator in the Neutral Beam Injector(NBI),a detailed analysis of the output voltage of capacitor-filtered three-phase bridge rectifier circuits is presented based on an analytical method. The influence of supply impedance and continuous supply current is considered in the analysis process,and the analytical expression is derived based on different circuit models. The results of simulation are shown to confirm the validity of theoretical analysis. This study provides a reliable basis for the design of the power supply of the NBI accelerator and other power rectifiers.更多还原
