摘要:
变频器的整流装置工作时,电网侧含有丰富的谐波电流,可利用无源滤波器降低入网谐波电流含量。文章提出了一种共磁芯电感设计方案,其网侧电感和变频器侧电感共用一个磁芯。与常规单独磁芯电感相比,该方案不仅降低了无源滤波器的成本并减小了体积,而且简化了吸收电路,在非低载工况下具有很好的谐波抑制能力和无功补偿效果;针对调谐支路,提出电流衰减系数概念,缩短了无源滤波器的开发周期,且无需仿真验证也能保证滤波器的性能。Matlab 仿真和实测验证了理论的正确性。
Abstract:
There are an amount of harmonic currents in the grid side as the rectifier of inverter working and passive filter is a good choice to reduce such harmonic currents. It proposed a new design scheme of common magnetic core inductance in which a common magnetic core is shared by the inductances of grid-side and inverter-side. Compared with the passive filter with independent inductance, it not only reduces cost and size of the passive filter, but also simplifies RC absorption circuit, showing remarkable harmonic suppression ability and reactive power compensation effect under both normal and heavy load condition. It presented a concept of current attenuation coefficient in the design of the turner circuit, which can shorten design period and guarantee the filter performance without simulation verification. Simulation and prototyping test results verify the correctness of this design.
