In this paper, DC converters for their use in the power supply system of a walking robot - hexapod are considered. The problem of energy conversion of robots of this class is an urgent problem, because the quality of the transformation will depend on the time of their autonomous operation, which in turn is an important factor influencing the range of applications of the robot. In addition to power supplies, the converter plays an important role in this. The less losses it will provide during the operation of the robot, the longer the robot will be able to move in space and perform useful work.
 In this regard, the analysis of existing circuit solutions was carried out - from the simplest versions of converters based on discrete components to more complex with the use of special chips. Based on the analysis, the advantages and disadvantages of certain types of converters were identified, directly for their use in the power supply system of a walking robot - hexapod.
 Among the main types of converters were step-down, as their efficiency is higher than the step-up. In addition, the analysis of the types of transducers showed that linear transducers have worse efficiency compared to pulse. In this regard, the main emphasis in the work is on pulse converters.
 Of the latter were selected converters built using special chips designed for use in converters, because compared to other circuit solutions, they allow not only to obtain stable current and voltage in wide ranges, but also have the ability to adjust them, making it easy to test on the model work different servos without replacing the converter. Due to the high values of the output current for the developed layout, you can do with one converter, which reduces the cost and simplifies the design as a whole. In addition, such solutions, compared to others, have less weight and size, which is positively indicated by the possibility of placing on the hexapod additional equipment or payload that the robot can carry in the process.
