REACTIVE POWER CORRECTION DEVICE Russian patent published in 2007 - IPC H02J3/18 B60L9/12 

FIELD: electrical engineering.

SUBSTANCE: proposed device designed to raise power factor of AC consist using band-phase voltage regulation to improve input current waveform and input-current reactive-power correction under all operating conditions of locomotive including other power consumers of locomotive and not only rectifier-inverter facilities has potential transformer, load in the form of rectifier-inverter assembly connected to traction motor, current and voltage sensor, phase detector, integrator, comparison gate, reactive power regulator, threshold element, switching unit, reactive-power source incorporating two capacitors and two chokes.

EFFECT: more complete correction of locomotive input reactive power, enhanced power factor.
