The chapter describes the structure of drive systems used in hoisting machinery of underground mines. These devices, due to their special application and power, are characterized by special traits. The most commonly used systems with DC reciprocating motors are described. The so-called complex (multi-pulse) converters are used in those solutions. An extra attention was paid to the impact of these systems on the power supply network, especially the generation of higher harmonics. The results of measurements made under real conditions are presented. Measurements were made before and after the installation of new solution in connection with the modernization of systems due to the need to increase the efficiency of these machines.
