An evaluation is performed for three-phase solar Photo-Voltaic (PV) inverters using either Silicon (Si) or Silicon Carbide (SiC) power devices. Standard and emerging topologies for high-efficiency (>98%) PV inverters are identified and optimized for the capital cost of power filter components and power devices. Analytical formulae are developed for minimum filter inductance considering both current...
The grid-connected photovoltaic generation system is the most important one in the field of photovoltaic application. In this paper, a model of photovoltaic has been constructed based on the main circuit of single phase grid-connected generation system using MATLAB/simulink to program it. The double closed loop control structure is adopted and forward-feed compensation method is employed to the system...
Effective control strategies for reliable photovoltaic (PV) grid-connected systems are needed to efficiently use solar energy, an abundant and clean renewable energy source. A space vector pulse width modulation (SVPWM) has been widely applied in the current control of three-phase voltage source inverters (VSIs). The control strategy combines a constant voltage tracking method for the variable photovoltaic...
