Abstract
Aiming at the disadvantage of inverter based on traditional SPWM modulation in power system, of which efficiency is not high and the reliability is bad, so SVPWM technology used in photovoltaic grid-connected inverter is proposed and its main circuit is simulated under the environment of Matlab/Simulink. Meanwhile the main control chip is TMS320F2812 and the main circuit is three-phase inverter module, based on SVPWM modulation technology, the single neuron PI voltage closed-loop control method is used to improve the output voltage wave quality of the Grid-connected inverter and a 220 V/50 Hz Grid-connected inverter is developed. According to the simulation results, they prove that the design is feasible and effective. And according to prototype experimental results, the designed Grid-connected Inverter has the advantages of simple hardware circuit, the low output voltage harmonic distortion and voltage stability.关键词
