Abstract |
|
In proposed grid connected PV system the single phase CSI converter used with a double tuned resonant filter circuit. The system uses transformer-less single-stage transformation for tracking the most extreme power point and interfacing the photovoltaic array to the grid. The greatest power point is kept up with a fuzzy logic controller. A proportional-resonant controller is used to control the current injected into the grid. A modified carrier based modulation technique for the current source inverter is proposed to magnetize the dc-link inductor by shorting one of the bridge converter legs after every active switching cycle. |
