摘要

本文提出了一种皮尔逊随机游走方法，用于模拟$N$并联电力电子变流器的电磁发射。本文首次提出了一种测试随机漫步方法的方法。该方法在两个方面得到了验证：首先，通过一个由8个半桥式电力电子变换器组成的简化装置的仿真。其次，使用由3个dc/dc转换器组成的实验装置对其进行验证。在复域进行验证，并通过理论累积分布函数和经验累积分布函数比较共模电流的幅值。最后，导出了开关频率某一特定谐波下电磁干扰减小的概率。

A Pearson's Random Walk Method of Estimating the Electromagnetic Emissions of $N$ Parallel Connected Power Electronic Converters

This article presents a Pearson's random walk approach for modelling the electromagnetic emissions of

$N$

parallel connected power electronic converters. For the first time, a methodology that enables testing the random walk approach is presented. This methodology is validated in two ways: firstly, via simulations of a simplified setup consisting of 8 half-bridge power electronic converters. Secondly, it is validated with the use of an experimental setup consisting of 3 dc/dc converters. The verification is done in the complex domain, as well as by comparing the magnitude of the common mode current via the theoretical cumulative distribution function and the empirical cumulative distribution function. Finally, the probability of electromagnetic interference reduction at a specific harmonic of the switching frequency is derived.
