Abstract

Abstract Translated from German Bei einem Leistungs-Schaltverstärker werden der Eingangssignalbereich (ESB) in eine Mehrzahl von gleichen Spannungsstufen (V1 ... V6) unterteilt und eine der Anzahl der Spannungsstufen (V1 ... V6) entsprechende Zahl von Schaltstufen (S1 ... S6) angesteuert und deren Gleichspannungsquellen (U1 ... U6) in Serie geschaltet. Durch eine variable Zuordnung zwischen den Spannungsstufen (V1 ... V6) und den Schaltstufen (S1 ... S6) ergibt sich eine gleichmässige Belastung aller Schaltstufen(S1 ... S6) und eine Reduktion der Schaltfrequenzen. In the case of a power switching amplifier, the input signal range (ESB) is divided into a plurality of identical voltage stages (V1 ... V6) and a number of switching stages (S1 ... S6) corresponding to the number of voltage stages (V1 ... V6) is controlled and their DC voltage sources (U1 ... U6) connected in series. A variable assignment between the voltage levels (V1 ... V6) and the switching levels (S1 ... S6) results in an even load on all switching levels (S1 ... S6) and a reduction in the switching frequencies.
