Der Wirkungsgrad dieser bekannten Stromrichterschaltung (Stromrichtertopologie) ist durch die Reihenschaltung mehrerer Subsysteme pro Stromrichterventil eines jeden Phasenmoduls allerdings begrenzt. Bei Verwendung von abschaltbaren Halbleiterschaltern, beispielsweise IGBTs bzw. IGCTs mit hoher Nennspannung von beispielsweise 3,3 kV, 4,5 kV oder 6,5 kV in den Subsystemen treten erhebliche Schaltverluste bei moderaten Durchlassverlusten auf. Werden Niederspannungs-IGBTs für beispielsweise 1200 V oder 1700 V eingesetzt, sind die Schaltverluste geringer, aber die resultierenden Stromrichterdurchlassverluste erheblich, da pro Stromrichterventil eines Phasenmoduls wegen der Niederspannungs-IGBTs eine höhere Anzahl von Subsystem verwendet werden müssen. Die Subsysteme dieser bekannten Stromrichterschaltung gehören zu den hartschaltenden Zweipunkt-Stromrichtern.Of the Efficiency of this known converter circuit (converter topology) is due to the series connection of several subsystems per converter valve however, limited by each phase module. When using switchable semiconductor switches, such as IGBTs or IGCTs with high rated voltage of, for example, 3.3 kV, 4.5 kV or 6.5 kV in the subsystems occur significant switching losses at moderate Pass losses on. Be low-voltage IGBTs for For example, 1200 V or 1700 V are used, the switching losses lower, but the resulting power converter passage losses considerably, because per converter valve of a phase module because of the low-voltage IGBTs a higher number of subsystem must be used. The subsystems of this known power converter circuit include to the hard-switching two-point converters.

Kern der Erfindung ist die Anwendung des bekannten sogenannten ARCP-Prinzips auf eine gattungsgemäße Stromrichterschaltung mit verteilten Energiespeichern. Dadurch ändern sich Schaltungsstruktur und Betriebsweise, d. h., die Kommutierung eines jeden Subsystems der Phasenmodule einer mehrphasigen Stromrichterschaltung. Durch die erfindungsgemäße Abänderung eines bekannten Subsystems erhält man ein sogenanntes ARCP-Subsystem. Im Vergleich zu einem gattungsgemäßen hart schaltenden Stromrichter mit verteilten Energiespeichern können die Schaltverluste eines erfindungsgemäßen Stromrichters mit verteilten Energiespeichern beispielsweise um mehr als 50% reduziert werden. Werden dann noch abschaltbare Halbleiterschalter verwendet, die für weiches Schalten optimiert sind, ist eine weitere Reduktion von Schaltverlusten möglich. Außerdem werden durch die Verwendung erfindungsgemäßer Subsysteme in einer Stromrichterschaltung mit verteilten Energiespeichern auftretende Spannungsänderungsgeschwindigkeiten deutlich im Vergleich zu hartschaltenden Stromrichter mit verteilten Energiespeichern reduziert.core The invention is the application of the known so-called ARCP principle to a generic converter circuit with distributed energy storage.

zweipoligen Subsystems
Neben diesen beiden ARCP-Kommutierungen existieren noch zwei sogenannte kapazitive Kommutierungen. Bei der einen kapazitiven Kommutierung kommutiert ein positiver Zweigstrom i0 vom abschaltbaren Halbleiterschalter S2 auf die Freilaufdiode D1 des abschaltbaren Halbleiterschalters S1. Diese Kommutierung wird durch das aktive Aufschalten des abschaltbaren Halbleiterschalters S2 eingeleitet und endet mit dem passiven Einschalten der Freilaufdiode D1.In addition to these two ARCP commutations there are two so-called capacitive commutations. In the case of capacitive commutation, a positive branch current i 0 commutes from the semiconductor switch S 2 which can be switched off to the freewheeling diode D1 of the semiconductor switch S 1 which can be switched off . This commutation is initiated by the active connection of the turn-off semiconductor switch S 2 and ends with the passive turn-on of the freewheeling diode D1.
Bei der zweiten kapazitiven Kommutierung kommutiert ein negativer Gleichstrom i0 vom abschaltbaren Halbleiterschalter S1 auf die Freilaufdiode D2 des abschaltbaren Halbleiterschalters S2. Diese zweite kapazitive Kommutierung wird durch das aktive Ausschalten des abschaltbaren Halbleiterschalters S1 eingeleitet und endet mit dem positiven Einschalten der Freilaufdiode D2 des abschaltbaren Halbleiterschalters S2.In the second capacitive commutation commutes a negative direct current i 0 from the turn-off semiconductor switch S 1 on the freewheeling diode D2 of the turn-off semiconductor switch S2. This second capacitive commutation is initiated by the active switching off of the turn-off semiconductor switch S 1 and ends with the positive turn-on of the freewheeling diode D2 of the turn-off semiconductor switch S 2 .
