Abstract


This article from the input and output characteristics of solar cells and single phase grid inverter system , expand the single-phase solar photovoltaic grid-connected inverter . The solar cell maximum power point tracking (MPPT) algorithm and inverter control is the key to single-phase solar PV grid inverter . First, from the smallest unit of the solar cell , the mathematical model of the solar photovoltaic array , and the basis of the mathematical model MATLAB simulation . Comprehensive comparison of existing photovoltaic arrays maximum power (MPPT) method , the maximum power point tracking solar cells based on the the Boost circuit duty cycle theory of improved incremental conductance method can better improve solar battery output efficiency has guiding significance . Through the analysis of solar photovoltaic grid-connected inverter based on the combination of the SVPWM control methods of the three-phase inverter circuit , the paper proposes a vector pulse width modulation (SVPWM) and beat algorithm of single-phase grid-connected inverter control program , the simulation model based on Matlab / Simulink and SABER single-phase grid-connected inverter deadbeat control algorithm . The simulation results show that almost all the harmonic content is reduced to less than 1% of the switching times has also been optimized , the control method is effective to improve the efficiency and output power quality of the grid-connected inverter system has certain use value . Finally built based TMSLF2407 grid-connected inverter hardware architecture , software design based deadbeat SVPWM control method and basis . The test results show that the deadbeat SVPWM control algorithm can effectively track the grid voltage and the reference current . Is an effective solar photovoltaic grid-connected inverter control method .
