Photovoltaics (PV) and fuel cells voltage of superior quality is a fundamental requirement. in particular are of special importance because of their This task is achieved by means of inverters, which “chop sustainability and environmentally friendly energy technol- up” the direct current voltage into energy packets of vary- ogy. In contrast to water and wind power, however, these ing sizes, reassembling it in the form of a sine wave with sources produce DC voltage which, in order to be used the appropriate line frequency (50 or 60 Hz) and amplitude commercially, must ﬁrst be transformed into AC voltage at (250 or 380 VAC). This transformation process, however, the appropriate line frequency. causes unwanted radiated interference, which may make it difﬁcult to meet the statutory requirements for power grid quality. Remedial measures are therefore crucial. This is where SCHURTER’s various products come into play. (see circuit diagram, nex
