Abstract

Osnovna razlika izmedju polumostnog pojacavaca sa podizacem napona prema ovom pronalasku i postojecih pojacavaca u klasi D se sastoji u povezivanju potrosaca (5) izmedju izvora (1) za napajanje i prekidackog polumosta (3) koji se napaja iz mostnog kondenzatora (6). Rad prekidackog polumosta (3) kontrolisu impulsno-sirinski modulisani kontrolni signal. Pri tome je moguce potpuno eliminisati ulazni i izlazni filtar koji su obasvezni deo postojecih pojacavaca u klasi D. Takodje je omoguceno postizanje visestruko vece snage na potrosacu (5) zahvaljujuci dodatnom napajanju prekidackog polumosta (3) iz mostnog kondenzatora (6). Konduktivne i radijacione EMI smetnje su znatno smanjene u odnosu na postojece pojacavace u klasi D. Ovakva realizacija omogucava nisku cenu, male gabarite pojacavaca i nizak nivo EMI smetnji.
