    Abstract:

    A comparative study of the properties of the isolated and non-isolated SEPIC converter is given. That includes voltage gain, efficiency, and input and output impedance as functions of the duty cycle. To our best knowledge some of these properties were studied for the first time here.



    Keywords:

    DC-to-DC converter, gain, duty cycle, efficiency, input impedance, output resistance
