The generation of high dc voltages is necessary for feeding many technical applications and testing the insulation material of high-voltage dc transmission lines and ac power cables with long lengths. The article proposes a modular multiplier high-voltage dc generator with integrated Cockcroft–Walton (CW) circuits. In this new topology, CW circuits are connected in series to produce a high dc output voltage with low regulation factor (<2%) and a negligible ripple factor without the need for costly filters to produce a nearly constant output voltage. The modules are fed by low input ac voltage sources that have the same magnitude and frequency. Numerical simulations using MATLAB/Simulink confirm the viability of the proposed generator. The generator is finally validated by experimental tests on a kV-size prototype.

串联高压直流倍增器的设计与模型

高压直流输电线路和长交流电力电缆的绝缘材料为许多技术应用供电和测试绝缘材料都需要产生高直流电压。本文提出了一种带有集成 Cockcroft-Walton (CW) 电路的模块化乘法器高压直流发电机。在这种新拓扑中，CW 电路串联连接以产生具有低调节因数 (<2%) 和可忽略的纹波因数的高直流输出电压，而无需昂贵的滤波器来产生几乎恒定的输出电压。这些模块由具有相同幅度和频率的低输入交流电压源供电。使用 MATLAB/Simulink 的数值模拟证实了所提出的生成器的可行性。发电机最终通过对 kV 尺寸原型的实验测试进行验证。
