摘要

Abstract

The high-voltage high-power press-packed IGBT (PPI) devices are the key component of the DC transmission apparatus. A PPI device is composed of several PPI submodules. In general

the PPI submodule works in a state of repetitive turn-on and turn-off

and the corresponding working voltage is the positive periodic square waveform (PPSW) voltage

which is much different from the conventional AC or DC voltage. In ad-dition

insulation capability is one of the most critical challenges in the design and fabrication of PPI devices. To improve the insulation capability of the device

composite insulation structures with multiple dielectrics are usually employed. Under the PPSW voltage

it is essential to analyze the transient electric field to solve the insulation challenge of the PPI devices. However

the electric field of the PPI is often calculated under the electrostatic field or DC field. Moreover

the transient characteristics of the electric field are ignored. Therefore

this paper focuses on the analysis of the transient characteristics of the electric field of the PPI submodule under the PPSW voltage. The influences of the waveform parameters of the PPSW voltage on the transient characteristics are demonstrated in detail. This study is significant for the insulation analysis and design of the PPIs.
