    Abstrakt

    Tto prca sa zaober nvrhom topolgie VPS pre bezdrtov prenos elektrickej

    energie. Proces vberu a nvrhu systmu je rozdelen do teoretickej a praktickej asti.

    Teoretick rozbor bol vykonan na zklade pokynov pre vypracovanie diplomovej

    prce a venoval sa najm pozadiu bezdrtovho prenosu zaloenho na princpe

    magnetickej rezonancie.

    V praktickej asti sa kldol draz na simulan model, v ktorom sa zisovalo

    sprvanie systmu ako aj napov a prdov namhanie siastok. Odsimulovan

    priebehy slili ako podklad pre experimentlne overenie navrhnutho systmu.

    Na zklade simulanho modelu bola zostaven fyziklna vzorka, ktor bola

    spene podroben meraniam.

    Diploma thesis deals with design of system for wireless power transfer. The aim of theoretical part

    is analysis of possibilities for wireless power transfer. Practical part consist of design system for

    wireless power transfer, which is used as simulation model and built for measurements on physical

    sample.
