TÓM TẮT
Nowadays, electricity demand significantly increases along with reduction of negative impacts to environment leads to a strong development of renewable energy which includes solar energy. In order to be able to provide power for the load, photovoltaic (PV) has to receive solar radiation to convert into electricity, through the converters to obtain such responses as voltage, frequency, etc. suitable for the load. However, this conversion creates the harmonics, one of the factors that reduce power quality and damages the devices. This paper studies two passive single-tuned and double-tuned passive filters coupled with converters for off-grid solar system. By means of simulation from Matlab/Simulink software, a solar conversion system and filters are built to meet the load requirements of 1kW and rated voltage of 220V. The results show that the double-tuned filter offers better harmonics filtering than the single-tuned filter, very low output voltage distortion for stable loads.
