Abstract: A kind of single step micro-inverter control system was designed. Aiming at disadvantages of traditional PI control which is unable to realize non-static-error control, this paper raised a quasi proportion resonance (PR) grid-connected strategy carrying out grid-connection currents non-static-error control and built a photovoltaic grid-connected micro-inverter simulation system based on Saber platform. Simulation result shows that the micro-inverter in adoption of quasi proportion resonance grid-connected control strategy has very good output voltage and current characteristics and the whole harmonic distortion ratio is less than the national standard of public grid harmonics.
Key words: micro-inverter; photovoltaic grid-connected; quasi proportion resonance control; Saber platform
