Adaptive multi-phase control system of the rectifier-inverter converter of electric rolling stock

Abstract

An analysis of the influence of the quality of electrical energy on the reliability and service life of railway devices and other objects was carried out. The shortcomings of the operation mode of thyristor rectifiers in static converters of single-phase alternating current electric locomotives have been determined. Simulation of different control modes of the rectifier-inverter converter of the electric locomotive was carried out. An adaptive multi-phase control system of the rectifier-inverter converter is presented using a diode arm connected in parallel with the rectified current circuit.
