چکیده
|
Solar energy produces dc power which needs to be converted into ac power for further required applications. the conversion process is done using cascaded multilevel inverter with less thd%. in this paper the simulation and analysing of the different cascaded h-bridge multi-level inverter were done in matlab/simulink software. the total harmonic distortion thd% in output voltage produced in 5-level, 7-level and 9-level inverters are obtained and compared. in fact, this inverter is installed and connected to a microgrid used to supply the block of faculty of mechanical and electrical engineering at tishreen university. the suggested multi-level inverter (5,7,9 levels) consists of bidirectional switches with pulse-width modulation technique (pwm). this study is considered as a part of an integrated research of a solar-wind hybrid system that has been modelled and connected to the grid of the studied block. the output voltage of the proposed inverter has sinusoidal form with a total harmonic distortion thd of less than 2%.
