Flyback converter for electric car

Zaporni pretvarač je jedan od neizostavnih elektroničkih sklopova u današnjoj elektronici. U ovom se završnom radu opisuje osnovni princip rada zapornog pretvarača te njegove nadograđene verzije, zapornog pretvarača s dva MOSFET-a (eng. Metal-Oxide-Semiconductor Field-Effect Transistor). Shemama, slikama i literaturom opisan je struktura klasičnog zapornog pretvarača te zapornog pretvarača koji se u ovom radu koristi (s dva tranzistora). Osim same funkcije rada obrađene su također mane i prednosti korištenja zapornog pretvarača, gubici te potencijalno smanjenje gubitaka sklopa, detaljna izrada transformatora te ne kraju i sama mjerenja na napravljenom sklopu.The flyback converter is one of the indispensable electronic hardwares in today's electronics. This final paper describes the basic principle of operation of a flyback converter with two MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistor). The structure of both flyback converter and flyback converter with two transistors are described by diagrams, pictures and literature. In addition to the principle of operation, the advantages and disadvantages of a flyback converter, losses and potential reduction of circuit losses, detailed construction of the transformer and finally the measurements on the made circuit are also discussed
