GRID CONNECTED SOLAR GENERATION SYSTEM USING ISOLATED CONVERTER

摘要

The present invention relates to a system-linked photovoltaic power generation system. According to an embodiment of the present invention, the system-linked photovoltaic power generation system comprises: an insulative DC/DC converter boosting power generated by a solar battery to output boosted DC power, in which maximum power tracking is performed to maximize efficiency of the solar battery; and an inverter to switch the boosted DC power into AC power to link the AC power to system power. According to the present invention, leakage inductance of a transformer can be used to construct a resonance circuit without adding an additional inductor for resonance to a photovoltaic power generation system. Therefore, the size of the photovoltaic power generation system can be reduced, and manufacturing costs can be lowered.
