Abstract

In this paper, a new accurate and comprehensive analytical model of harmonic and interharmonic distortion produced by a single-phase AC/DC diode bridge rectifier (DBR) is presented. Its main and new characteristic is the ability to consider the presence of interharmonics in addition to harmonics in the voltage at the terminals of DBR due to the background distortion. Analytical expressions able to predict DC voltage and AC current either in time or frequency domains are obtained. Several numerical and experimental tests have been performed showing very accurate results. The proposed model presents all the advantages of analytical models (e.g., fastness); therefore, it can be easily integrated with iterative harmonic and interharmonic analysis procedures. Subsequent applications are the possibility to perform parametric analyses and probabilistic studies, to derive harmonically and interharmonically coupled admittance matrices, to help in introducing standard limits for interharmonics.

电源电压存在间谐波时单相二极管桥式整流器的新解析模型

本文提出了一种新的准确、全面的分析单相交/直流二极管桥式整流器谐波及谐波间畸变的分析模型。它的主要特点和新特点是除了考虑DBR端子电压中由于背景失真而产生的谐波外，还考虑了间谐波的存在。得到了直流电压和交流电流时域和频域的解析表达式。进行了一些数值和实验测试，结果非常准确。提出的模型具有解析模型的所有优点(例如，牢度);因此，它可以很容易地与迭代谐波和谐波间分析程序集成。随后的应用是进行参数分析和概率研究的可能性，推导谐波和间谐波耦合导纳矩阵，以帮助引入间谐波的标准限值。
