Optimized Stray Inductance Extraction Method of Bus Bar in Large-Capacity Power Electronic Equipment
摘要
Abstract
In large-capacity power electronic equipment, the stray inductance of the bus bar will not only cause higher voltage peak but also bring serious EMI issues during the commutation process. Thus, the stray inductance needs to be calculated accurately to analyze and optimize the system performance. Compared with the conventional differential method, the integral form is insensitive to the shape of the current waveform and has anti-noise ability. However, the results are greatly influenced by the boundary of integral. In this paper, an improved integral form of inductance extraction method for the bus bar is proposed. Herein, both the stray resistance and the measuring bias are considered to improve the calculation accuracy. Moreover, a double-pulse testing platform for the 1200V/3600A IGBT is built. The stray inductance is extracted through different methods to verify the effectiveness and the accuracy of the proposed method.关键词
