| Abstract: | A mathematical model of single-phase high power factor PWM rectifier and the digital deadbeat control algorithm were studied. A deadbeat current control strategy was proposed, which is used in double-stage and single phase photovoltaic grid-connected inverter. The simulation results show that the control method can transport the energy of PV cells as much as possible,and the output current can track the power system voltage quickly and accurately, and the power factor is close to 1. The method is reliable and accurate, it can he used to the field of photovoltaic. |
