Abstract

Innmatingskobling uten transformator for et vekselstrømskjøretøy. Ifølge oppfinnelsen har innmatingskoblingen uten transformator på inngangssiden to to-polede brytere (2, 4) og på utgangssiden en selvstyrt strømretter (6) med påtrykt spenning (Uzw), hvor den ene to-polet bryter (2) oppfører seg kapasitivt og den andre to-polede bryter (4) oppfører seg induktivt i forhold til nettets grunnsvingning (fN), hvor begge to-polede brytere (2, 4) på inngangssiden er elektrisk ledende koblet til hverandre og på utgangssiden er hver koblet til respektive vekselstrømstilkoblinger (A, B) i den selvstyrte strømretter (6), og hvor den selvstyrte strømretter (6) har to fasemoduler (12) og to elektrisk seriekoblede kondensatorer (Cp, CN) med jordet forbindelsespunkt (14). Derved fås en innmatingskobling uten transformator for et vekselstrømskjøretøy, som ikke krever høye strømretterprestasjoner og ingen høye kostnader, og hvorved isolasjonsbelastningen for denne innmatingskobling halveres.Input connection without transformer for an AC vehicle. According to the invention, the input connection without transformer has two two-pole switches (2, 4) and on the output side a self-controlled current inverter (6) with applied voltage (Uzw), where one two-pole switch (2) behaves capacitively and the other two-pole switch (4) behaves inductively with respect to the network's fundamental oscillation (fN), where both two-pole switches (2, 4) on the input side are electrically conductive to each other and on the output side each are connected to respective alternating current connections (A, B) in the self-controlled current converter (6) and wherein the self-controlled current converter (6) has two phase modules (12) and two electrically connected capacitors (Cp, CN) with grounded connection point (14). Thereby, an input coupler without a transformer is obtained for an alternating current vehicle, which does not require high rectifier performance and no high costs, thereby halving the insulation load for this input coupling.
