Abstract

Definiran je način rada pojačala klase D, definiran je pojam elektromagnetske kompatibilnosti. Opisane su zadane norme za razine smetnji. Definirane su metode mjerenja vođenih i zračenih smetnji. Analizirana je električna shema i dizajn tiskane pločice. Opisani su uvjeti i parametri mjerenja te su prikazani rezultati mjerenja vođenih smetnji pomoću 150-Ohm metode i zračenih smetnji izmjerenih u TEM ćeliji. Provedena je analiza dobivenih mjerenja te usporedba s rezultatima iz drugog izvora.

Abstract (english)

Working principle of class D amplifier and the electromagnetic compatibility are defined. International norms for interference levels are stated. Conducted and radiated interference measuring methods are defined. Circuit diagram and printed circuit board design are analysed. Measuring method and it's parameters were defined and the results of the following measurements were shown. Given results were analysed and compared with other results from another source.
