Abstract

Strømforsynlngsomformer med en brokoplet effekt- forsterker drevet av en enkel likestrømsinngangs- strømforsyningskilde via en flerhet av parallell- forbundne PWM-motkopleromformere. Omformerne er modulert med referanseslgnaler som opererer i tids- alternering slik at ved en hver omformingssyklus finnes det en flerhet av modulerende bølgeformer, som er Identiske med unntak av deres tidsforsinkelse og som er Jevnt anbragt i tid over en enkel omformingssyklus. En tilbakekopllngsforsterker sammenligner spennlngsut- gangen til parallellforbundne omformere via størrelsen på forsterkerens kreve forsyningsspennlng og driver modulasjonskomponenten til kretsen for styresvitsj- arbeldssyklysen til hver av de enkelte PWM-omformerne.
