摘要:针对单相集成充电器交流侧和直流侧功率不平衡的问题,通过定量计算得出直流侧电压中存在二次谐波脉动。为了分析和减弱二次谐波的影响,首先将二次谐波带入到控制系统中得出二次谐波会使交流侧电流中产生奇次谐波;然后在直流电压控制环中加入带阻滤波器,对输入到控制系统的直流电压进行滤波。最后,在Matlab/Simulink应用环境下对系统进行建模和仿真,仿真结果证明了该滤波方法的可行性。
关键词:功率不平衡;二次谐波脉动;交流电流;带阻滤波器;滤波
Abstract: For the power imbalance of AC side and DC side in singlephase integrated battery charger, quantitative calculation is made and the conclusion that there is secondharmonic in DC voltage was drawn. In order to analyze and weaken the influence of secondharmonic, first of all, the secondharmonic was brought into the control system and the result that secondharmonic will generate odd harmonics in AC current was received; and then, the band resistance filter which is added to the voltage control loop was adopted to reduce secondharmonic of DC voltage in control system. Finally, the Matlab/Simulink simulation model was built up. The results verified the validity of the proposed method.
Key words: power imbalance; secondharmonic; alternating current; band resistance filter; filtering
