Concept of electronically controlled inductor realized by experimental card LN SO4204-7N

Jednofazni izravni izmjenični pretvarači napona spadaju u najjednostavnije pretvaračke sklopove koji omogućuju upravljanje efektivnom vrijednošću struje trošila promjenom kuta okidanja. U ovom radu, prikazana je analiza rada izmjeničnog pretvarača napona opterećenog radnim i induktivnim trošilom. Također, provedena su mjerenja na izmjeničnom pretvaraču u slučaju radnog i induktivnog opterećenja s ciljem promjene induktivnosti prigušnice. Koncept elektronički upravljane prigušnice podrazumijeva upravljanje induktivnošću prigušnice promjenom kuta okidanja. Snimljeni su valni oblici napona i struje trošila koji su kasnije uspoređeni s valnim oblicima dobivenim u provedenoj analizi rada. Sva mjerenja obavljena su uz pomoć didaktičko multimedijalne opreme Lucas-Nülle i programa LabSoft.Single-phase direct AC voltage converters are among the simplest converters that enable the control of the RMS value of the consumer current by changing the trigger angle. In this paper, an analysis of the operation of an alternating voltage converter loaded with a working and inductive consumer is presented. Also, measurements were performed on the AC converter in case of operating and inductive load with the aim of changing the inductance of the electric coil. The concept of electronically controlled inductance involves controlling the inductance by changing the trigger angle. Voltage and current waveforms were recorded, which were later compared with the waveforms obtained in the performed analysis. All measurements were performed with the help of the Lucas-Nülle didactic multimedia equipment and the LabSoft program
