要約(英語): The power electronic equipment usually operates in high-frequency voltage environments, under which the charge characteristics of the insulating materials have not been studied in detail. Based on the pulsed electro-acoustic method, the traditional circuit design used for DC voltages is firstly discussed. Simulated results indicate that the selection of the protection capacitor of 187 pF and the resistor of 333 kΩ is more proper for high-frequency application environments compared to the traditional one. Further experimental results find that, the charge amount under sine and half-wave sine voltages are larger than that under DC voltages, which is more obvious at the frequency of 10 Hz. The maximum electric field distortion appears under the sine voltage, whose values are 68.55 and 81.82 kV/mm at 90 and 270 degrees, respectively. The results can provide guidance for future application of insulating materials in electronic equipment.
