This paper proposes a control strategy for single-phase off-grid inverter, which integrates the three clo-sed-loop control with the iterative-based RMS algorithm. The inverter circuit is modeled, and simulation experiment and prototype verification are performed on Matlab.
A common control method for off-grid inverters is multiple-loop control with a PI compensator. The output of the voltage loop is the reference value for the current loop. In this model, the common control method is utilized except that the voltage reference and sampling signal is the RMS value of output voltage.
Thus, the single-phase off-grid inverter adopting the three closed-loop control stra-tegy can address the voltage drop problem caused by abrupt load variation [6,12].
Meanwhile, the application of iterative method enhances the dynamic response perfor-mance of the system substantially; and improves the real-timeliness of three closed-loop control. The two complement each other to provide a highly effective, reliable control solution for the single-phase off-grid inverter.
