Novel Skip Control Method for Improving the Efficiency of Micro-Inverters Under Light Load Conditions

  Ming-Hung Yu,  Paul C.-P. Chao

This paper presents a novel skip control method for improving the efficiency of micro-inverter at low power inputs. The proposed control method assesses the operating mode of a system according to the energy of an input capacitor. If the energy is higher than a reference level, the system operates in a continual mode; otherwise, the system operates in a discontinue mode to improve the light load efficiency. Finally, a 200-W micro-inverter is implemented to verify the proposed control method, The implemented micro-inverter was used in an experiment to compare the efficiency of operations with and without the proposed skip control method. This comparison was conducted to verify whether the proposed skip control operation improved the operating efficiency under light load conditions.

Keywords- micro-inverter, skip control method, light load, photovoltaic.
