摘要

Abstract

In this paper

a novel numerical method called interface finite volume method (I-FVM) for calculation of step-varying Electro-quasistatic (EQS) field is proposed. First

the principle of I-FVM is derived. Then

with numerical example of double layers parallel plate structure under step voltage which has an analytical solution

effectiveness and correctness of the I-FVM are verified. It can be found the calculating time of I-FVM is only 30% of normal FVM without decreasing accuracy during the whole calculating process. Furthermore

an engineering example about the electric field of DBC (Direct Bonding Copper) structure in a high voltage IGBT device is given. It can be found that accuracy of the I-FVM is the same as normal FVM

while time cost of I-FVM is only 20.8% of normal FVM. At last

the I-FVM is extended to one dimension based on the two-direction tri-diagonal matrix algorithm (TDMA) method given in this paper which can save processing of LU decomposition compared to one-dimensional traditional TDMA. In conclusion

the novel method called I-FVM proposed in this paper can decrease calculating amount for a step size varying electro-quasistatic field calculation problem. It may be a good method for large-scale EQS field calculation.
