“…Consideration of different chargeup voltages is justified by the fact that the different energy levels can be sufficient for good operation, while degradation of the capacitor can be strongly accelerated by higher bias voltages [4]. The temperature range À55 to 25°C is dictated by a requirement for functionality; exploration of higher temperature levels aims to assess the impact of temperature on the degradation rate of the component [6].…”

“…In high-repetition-rate applications, the heat can be reduced by reducing the metallization resistivity, but at the cost of reduced energy density [6]. Kong et al [11] presented a model to estimate the temperature rise of the film in the duration of a single discharge and concluded that the maximum temperature rise was quite small after a single discharge. But the accumulation process of heat produced by repetitive pulse current was not taken into consideration in calculations.…”

The problem of non‐uniform voltage distribution in the internal element of metallized film capacitors in flexible HVDC transmission systems exists, the influence of electrical parameters of dielectric and metal copper row are not considered in the existing metallized film capacitor equivalent circuit model. In this paper, the conductance of biaxially oriented polypropylene film (BOPP) for metalized film capacitors is measured at different electric field intensity and dielectric properties at different frequencies. The current density distribution and voltammetric properties of the metalized film capacitor elements under AC and DC superimposed voltages are calculated by the finite element method, and the voltammetric properties of the copper row considering the skin effect are derived. The equivalent circuit model of the metalized film capacitor under the AC‐DC superposition voltage is proposed. The simulation results of the capacitor equivalent circuit model show that the voltage distribution of the internal elements of the capacitor is uniform at low frequency AC voltages (<102 Hz), and the voltage amplitude and phase difference between the elements of the capacitor gradually increases with increasing AC voltage frequency. At an AC voltage frequency of 105 Hz, the difference in magnitude between the two capacitor elements on the same copper row was up to 2.01% and the phase difference was 13.5%, while the difference in magnitude between capacitors at the same horizontal position on different copper rows was up to 56.8% and the phase difference was 10.44%. The results of this paper provide some guidance for the modeling of the internal components of metalized film capacitors, the calculation of voltage distribution and the structural optimization design.
