Analysis of the Energy Characteristics of the Traction Substation Rectifier

Abstract

The analysis of the electromagnetic processes of a rectifier unit with a controlled pulse-width modulation with a booster rectifier is carried out. An expression for the power factor of a rectifier unit is obtained by an integral method for determining reactive power. It is shown that the adjustable pulse width modulation parameter has little effect on the power factor. The power factor is greater than with phase control.
