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.
By establishing the mathematical model of the single-phase inverter, the current inner loop control can obtain rapid dynamic performance, and the voltage outer loop control can improve the steady-state performance of the system. Secondly, using the pole configuration method, the parameters of the double closed-loop PI can be obtained.
A typical inverter comprises of a full bridge that is constructed with four switches, which can be modulated using pulse width modulation (PWM), and a filter for the high-frequency switching of the bridge, as shown in Figure 1. An inductor capacitor (LC) output filter is used on this reference design. Figure 1. Typical Single Phase Inverter
