RECTIFYING VOLTAGE STABILISER Russian patent published in 2012 - IPC H02J5/00 

FIELD: electricity.

SUBSTANCE: rectifying voltage stabiliser is intended for conversion of three-phase AC 380 V, 50 Hz into DC voltage 27 V to supply different loads in electric systems for wheel- and track-mounted mobile control complexes. Article is intended for operation in conditions of group 1.3, 1.4.1 as per GOST RV 20.39.304-98 with limitation of low operating temperature of - 233 K (minus 40°C). Device has connectors purposed for article switching to three-phase mains, for remote switching on/off of article and uniting of several current sensors at combined action for total load and for voltage drop compensation at interconnecting wires, fuse-holders for 10 A, ground terminal, clamp connections 27 V doe load connection to rectifying voltage stabiliser.

EFFECT: possibility of rectifying voltage stabiliser connection for parallel operation, voltage drop compensation at interconnecting wires, high reliability of article in severe environment, high efficiency factor, built-in control of output voltage and load current, possibility of load connection with any grounded pole.
