This paper presents a Matlab/simulink model of grid-connected photovoltaic (PV) system, including a PV array, a control system, a distribution network and a load. Based on the accurate modeling system, optimum control and stability analysis are studied. The current control strategy can regulate the current at the point of common coupling to achieve the power factor control. The voltage control strategy...
The mathematical and simulation model of three-phase voltage source rectifier (VSR) used in aircraft is introduced in this paper. Based on the model, the principle of the seven-segment space vector pulse-with modulation (SVPWM) control strategy is presented. The double closed-loop control method is applied in the PWM rectifier. The rectifier can realize unity power factor by adopting the fixed switching...
PWM rectifier is called green energy conversion device, it can be widely used in motor control field for the steady DC bus voltage and unit power factor. The waveforms of DC bus voltage and input current are simulated and analyzed for different load and power network of different parameter. The control strategy is provided based on MFAC, and the PWM rectifier system of voltage-source current-control...
