In this letter, a novel damped AC (DAC) generator is proposed and implemented, whose working principle is based on the seamless combination of the high voltage (HV) DC source and the HV solid switch by replacing the diodes in the DC voltage multiplier (VM) with controllable insulated gate bipolar translators (IGBTs). Both laboratory tests on a lumped capacitor and field tests on a 10 kV MV cable were performed to prove the feasibility of the proposed techniques.

用于中压电缆绝缘的PD测试的新型DAC发生器

本文提出并实施了一种新型的阻尼交流（DAC）发电机，其工作原理基于高压（HV）直流电源和HV固态开关的无缝组合，方法是替换直流电压倍增器中的二极管（ VM）和可控的绝缘栅双极转换器（IGBT）。进行了集总电容器的实验室测试和10 kV中压电缆的现场测试，以证明所提出技术的可行性。
