大带宽三环控制器在并网逆变器中的分析与实验表征

This paper analyzes a large-bandwidth, triple-loop controller designed for single-phase, grid-tied, and voltage–source inverters with LCL output filter. The inner control loops regulate the inverter output current and the filter capacitor voltage, respectively, while the third, outer one regulates the current injected into the grid. The inner loops are given deadbeat type regulators, whose minimum...
