    摘要: Zum Antakten eines drei- oder mehrphasigen Stromrichters (SR) mit Phasenfolgelöschung, der mit einem eingeprägtem Zwischenkreisstrom (la) gespeist wird, wird der Zwischenkreisstrom (Id) zunächst auf kleine Werte begrenzt und die Taktfrequenz auf ihren von der Steuerung vorgebbaren Maximalwert erhöht. Sobald die Spannung an den Kommutierungskondensatoren (C K ) eine ausreichende Höhe erreicht hat, wird der Zwischenkreisstrom (l d ) zeitverzögert auf den Anfahrwert erhöht und anschließend die Taktfrequenz nach einer Zeitfunktion auf die optimale Anfahrfrequenz reduziert.
