This paper presents comparative investigation of both voltage and current fed buck converters. This comparison takes into account the controllability, efficiency and size of the converters. The first section of the paper briefly describes a standard voltage fed buck converter. Transformation of voltage fed buck converter into the current fed converter is presented next. Then the operation of current fed buck converter is discussed. On the next stage experimental estimation of current fed buck converter is described. Finally conclusions about current fed buck converter with LEDs are drawn.
