Development of the сonverter structure that enables power supply to traction induction motors of mine electric locomotives from different levels of voltage

Abstract

Electrical equipment, including components of traction electric drives for mine electric locomotives, as well as the electric locomotives themselves, are produced in more than 15 countries by 30 firms that are leaders in this industry [1].However, it should be noted that only a small part (about 10%) of contact and accumulator-based mine electric locomotives is equipped with induction traction electric drives. Other types of electric rolling stock are equipped with ineffective traction electrotechnical complexes (TETC) with contact-resistor control systems and series-wound.
