摘要
在大功率电力电子设备中,由于受到体积重量的限制,低次谐波的滤除较为困难,采用谐振滤波器可在基本不增加设备体积重量的情况下,有效抑制特征谐波。首先介绍了谐振滤波的基本原理,然后针对三相整流桥输出特征谐波计算了相应的参数,并利用Simulink仿真模型验证了参数计算的正确性,最后通过实验验证了所提谐振滤波方法的有效性。
Limited by the volume and weight,it is a difficult task to restrict the low-frequency harmonic interference in high-power power electronics equipment.The resonance filter can effectively reduce the specific harmonic without adding the weight and volume of equipment.Firstly,the basic principle of resonance filter is introduced, then in view of the three-phase rectifier, output characteristic harmonic element parameter of the fiher is calculated, and the cor- rection of parameter calculation is simulated with the Simulink simulation model.FinaUy, the effective of the resonance filter is verified by the experiment.
