电流注入型18脉波三角-多边形自耦变压整流器
18-Pulse Delta-polygon Autotransformer Rectifier with Current Injection
摘要
Abstract
In a multi-pulse rectifier system,the harmonic content of input currents can be further reduced by the tech?nique of active harmonic suppression in the DC side.Based on an 18-pulse delta-polygon autotransformer rectifier,an active harmonic suppression method is adopted for the injection currents in the DC side.The compensation principle of injection currents is analyzed,and the realization method of injection currents is studied.A model of rectifier circuit is built,and simulation results show that the harmonic content of input currents from the power grid is kept below 3% when the load changes and an unbalance of three-phase voltage occurs;moreover,the influence due to unbalanced volt?age is also reduced.In this way,the harmonic suppression performance of the rectifier is improved together with a lower manufacturing cost.关键词
