How to control a grid connected inverter?Different control strategies are used to control the grid connected inverter. Inverter output current and grid voltage should bein phase. To achieve unity PF. Inverter output current should be pure sinusoidal. Total Harmonic Distortion of inverter current should be less than 5%.
What is a common control method for off-grid inverters?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.
How to improve the output voltage accuracy of an off-grid inverter?The off-grid inverter with the inverter side voltage as the feedback parameter has the advantages of a single voltage loop, simple control parameter design, and low cost.
