摘要：the formation of the input voltages \Σbici bi at the entrance of ainvertierers (63) are summed.in addition, the tension on a switch, and a bi
proportionalglied on receipt of a gl\ättungsgliedes (61) with the invertierer - outputsignal are summed.the switches are in accordance with the factors of ci
breitenmodulierten schaltimpulsen actuated. the calculated sum is located at the exit ofthe gl\ättungsgliedes.such a vektoranalysatoren and vektordreher allowfeldorientierte control of rotating field machines with high accuracy.
