“…Because with the increasing of length of the test cable, the devices of AC test become larger and heavier. Very low frequency (VLF) test system developed rapidly in recent years, which has a very good equivalence of AC test [1]. Not only withstand voltage test but also measuring of the dielectric loss Angle and partial discharge of the cable can be carried out by using VLF test system, so that comprehensive analysis on the status of the cable can be made easily.…”

with the rapid growth of the using of power cables in distribution network, a large demand for mobile high-voltage cable test systems is expected in the near future. VLF test system has a great equivalence of AC test, so it is wildly used in power cable test. In this paper, a novel VLF high voltage generator, based on LCC resonant converter, is introduced detailed. The Extended Describing Function (EDF) is used to select parameter of LCC resonant converter. In order to generate a true sinusoidal test voltage, the control strategy, concluding changing duty cycles of LCC resonant converter and load resistors, is proposed. The generator can generate a sinusoidal test voltage of 20 kV at 0.1 Hz and the result shows that the total harmonic distortion can meet the requirement of IEEE 400.2 standard.
