Compact Filter and Its Harmonic Filtering Performance Analysis
摘要
Abstract
Considering that the physical size of passive harmonic filtering units is usually confined in practical applica⁃tions,a new method for the compact design of passive filter and rectifier transformer is proposed. First,the correspond⁃ing decoupling mechanism of compact filter is analyzed theoretically. Then,based on the finite element model of a 300 kV·A transformer prototype in Ansoft,the coupling coefficients of prototype windings and the inductances of compact filtering reactors are evaluated using the reduced-order inductance matrix method. Finally,the prototype is applied to a practical rectification system. From the comparison of simulation and experimental results,it is indicated that the har⁃monic suppression performance of the presented filter is evident. Moreover,compared with the conventional passive fil⁃ter,the physical size of the filtering system is effectively reduced,which is applicable to cases with limited space for rec⁃tifier units.关键词
