Abstract

U radu se obrađuje prilagođenje električne impedancije hidroakustičkoga piezoelektričnog pretvarača pomoću električnog transformatora i LC transformatora na valni otpor električnog kabela antene spojenog na elektronički sustav primo/predaje sonara. Koristeći model idealnog električnog transformatora i električnog LC transformatora, dobivene su posebne formule koje omogućavaju točan izračun potrebnih elemenata za izvedbu i potpuno prilagođenje modula električne impedancije i faznog kuta.

The subject of this paper is matching electrical hydroacoustic piezoelectric transducers, by means of an electrical transformer and a LC transformer, to the wave resistance of an antenna electric cable, which is connected to transceiver sonar. By using the ideal transformer model and LC transformer, special formulas were gained, which enables the correct computing of elements necessary for performance and complete matching of electrical impedance and the phase angle.
