CONVERSION SYSTEM FOR AUXILIARY POWER SUPPLY OF GAS TURBINE LOCOMOTIVE Russian patent published in 2017 - IPC B60L1/00 B60L11/02 H02M3/04 H02J7/14 

FIELD: electricity.

SUBSTANCE: conversion system for auxiliary power supply of gas turbine locomotive comprises a control unit, two power supply inputs with DC voltage and two branches for the conversion of input power supply voltage. Each branch includes n-number of converters and n-number of galvanic isolation units. At the same time, joint outputs of all the galvanic isolation units are the output for the power supply of gas turbine locomotive auxiliary loads network. The output of the galvanic isolation units is connected to the output for the 480 V battery charge via the current sensor. The galvanic isolation unit outputs are connected to inputs of the two step-down-type DC voltage pulse converters with galvanic isolation. Joint pulse converter outputs are the power supply output for the circuits of control, lighting and charging the 110 V battery.

EFFECT: uninterrupted power supply for auxiliary equipment, on-board network and battery charge.
