Abstract

Thyristor rectifier-inverter converters are widely used. The power factor of the standard converter of locomotives does not exceed 65% in this mode, which does not meet the requirements of the national standard for electric locomotives with collector traction motors. This fact is due to the need to turn on the thyristor in advance, in the wrong half-period, from the point of view of energy transfer to the electrical network. Such turning-on of the converter leads to a large amount of reactive energy transmitted to the electrical network by an electric locomotive. The purpose of this work is to compare the modes of the standard and new rectifier-inverter converters. The new rectifier-inverter converter in the recovery mode works with switching of the diode–thyristor branch and with a new algorithm of operation. Both the mathematical model of converters and physical models are investigated.
