摘要
提出利用LCL滤波器对双Buck并网逆变器滤波。LCL滤波的双Buck并网逆变器既有LC滤波的无桥臂直通、可靠性高、器件耐压应力要求低等优点,又保证滤除系统的高次谐波,减小总电感体积。首先分析了LCL型双Buck并网逆变器的工作模态,然后设计LCL的参数等,最后分析了系统稳定性。并且用实验进行验证。
This paper presents a kind of dual buck photovohaic grid inverter with LCL filter. Dual buck inverter of LCL type is no shoot-through, high reliability, low breakdown voltage stress, and by improving the filter from LC into the LCL filter, it improves the filtering system on harmonic generation. Moreover, the volume and weight of filter inductor is lower. In this paper, a detailed analysis about dual buck connected inverter of LCL type working mode is carried out in first. Secondly, the parameters of system are designed. At last, the stability of the system is analyzed in detail. The experiment has verified the above analyses.
