【摘要】 提出基于SVPWM技术的串联混合型有源电力滤波器(SHAPF),并详细介绍了其原理、设计和应用。该有源电力滤波器实现简单,无复杂的矢量变换,且通过引入零矢量,在一个开关周期内减少了开关次数和损耗。由于直流母线电压利用率高,逆变器的谐波含量小,因此可提高串联有源滤波器的滤波效果,通过仿真及实验验证了该方法的正确性。更多还原

【Abstract】 In this paper,the series hybrid active power filter(SHAPF) based on SVPWM is described,and its principle,design and application are introduced in detail. Simple and uncomplicated vector transformation is achieved by the active power filter and the switching numbers and loss are reduced within one switching cycle by the introduction of zero vectors. Meanwhile,the filtering efficiency of the SHAPF can be improved due to the higher utilization rate of DC busbar voltage and the smaller harmonics of inverters. Finally,the correctness of the method is verified through simulation and test.更多还原
