ELECTRIC POWER SUPPLY FOR AXIAL SYMMETRICAL FIELD Russian patent published in 1994 - IPC

FIELD: power supply systems. SUBSTANCE: multiphase controlled rectifier converters have to be power supplies of windings, so voltage of the converters may be reduced due to increase in angles of regulations of the rectifiers of these converters. Two multiphase controlled rectifier converters 3 and 4 are connected in series. Any converter is designed on half a load voltage. Multiphase controlled rectifier converter 3 operates at positive angle of control, and converter 4 - at negative one. Angles of regulation of multiphase controlled rectifier converters are set in such a manner, that total current, consumed from the network by multiphase controlled rectifier converters mates in phase with voltage, i.e., reactive power is not consumed. Thyristor switches 5, 15, 16 allow to switch output wires of multiphase controlled rectifier converters 3 and 4 to parallel connection from series connection. EFFECT: reduced designed power of anode transformers. 1 dwg
