FIELD: machine building; electricity.
SUBSTANCE: invention relates to power supply to auxiliary equipment of transport facilities. Device for voltage stabilization in the supply system of asynchronous auxiliary machines of AC electric locomotives consists of a booster transformer with a sectioned high-voltage winding connected to leads of a power winding of a traction transformer through two-key switches. Two-way switches are controlled by a microprocessor device which receives information on the voltage level at the outputs of the electric locomotive winding from the voltage sensor.
EFFECT: technical result consists in improvement of operating reliability of auxiliary machines of AC electric locomotives.
