首先建立独立/并网模式下逆变器滤波高频模型,得出输出电压与并网电流的谐波计算公式。依据公式进一步分析滤波电感电容等参数与谐波抑制的关系,给出设计原则。通过设计实例,详细阐明设计原则及步骤,在综合考虑独立/并网模式下电压及电流谐波标准及控制稳定性等要求下,绘出设计曲线,得到性能成本最优设计参数。最后通过10kW逆变实验,验证了此设计方案的有效性。
First of all, the high frequency model of inverter filtering in independent / grid-connected mode is established, and the harmonic calculation formula of output voltage and grid-connected current is obtained. According to the formula, the relationship between the parameters of the filter inductor and the harmonic suppression is further analyzed, and the design principle is given. Through design examples, the design principles and steps are explained in detail. Under the requirements of voltage and current harmonics standards and control stability in independent / grid mode, the design curves are drawn and the optimal design parameters of performance cost are obtained. Finally, through the 10kW inverter experiment, the validity of this design scheme is verified.
