Compontents & Solutions for Renewable Energy Technology - 1

Irrespective of the technology used, an alternating current voltage of superior quality is a fundamental requirement. This task is achieved by means of inverters, which chop upӔ the direct current voltage into energy packets of vary- ing sizes, reassembling it in the form of a sine wave with the appropriate line frequency (50 or 60 Hz) and amplitude (250 or 380 VAC). This transformation process, however, causes unwanted radiated interference, which may make it diffi cult to meet the statutory requirements for power grid quality. Remedial measures are therefore crucial. This is where SCHURTERs various products come into play. > Application Areas Uninterrupted electricity supply represents a key chal- lenge in the 21st century. Photovoltaics (PV) and fuel cells in particular are of special importance because of their sustainability and environmentally friendly energy technol- ogy. In contrast to water and wind power, however, these sources produce DC voltage which, in order to be used commercially, must fi rst be transformed into AC voltage at the appropriate line frequency.
