X-RAY TUBE AND METHOD OF CONTROLLING X-RAY FOCAL SPOT USING THE SAME

摘要

According to the present invention, a photovoltaic power generation system includes a solar cell; a convertor connected to the output terminal of a solar cell; a capacitor connected to the output terminal of the convertor; an inverter changing DC voltage into AC voltage and connected to the capacitor; and a control part for controlling the inverter by controlling voltage in a determined rage and detecting the voltage (Vd) of the capacitor.
