The goal of this Bachelor´s thesis is design of an power inverter for BDC motor 36 V/800 W with permanent magnets. The first part of this work is devoted to the brief description of drive elements, which with designed converter create drive system. It´s also contain measures of used BDC motor MY1020. In the second part there is a outline description of functions and connection of DC/DC converters with respect to the final solution. The power circuit will be built with the MOS-FET IRFP4110 connected to the H bridge. Transducer control logic will be provided by the microcontroller development board Arduino UNO 3 with the integrated driver circuit IR2110
