| Abstract: | In this paper the withstand voltage test method of the equivalent pulse with control of LC series resonance voltage is introduced according to the capacitance characteristics of XLPE cable.It proves that the load capacitor which adopts equivalent pulse with control technology can also obtain sine wave voltage by theory analysis and calculation.The theoretical analysis is simulated,which proves it is correct.The control circuit system which is based on SG3525 chip is tested.The experimental result shows that the performance of each part of the circuit satisfies expected requirements. |
