METHOD FOR EXCITING TRANSFORMER IN POWER SUPPLY SYSTEM AND CONTROLLER FOR POWER CONVERTER

摘要

PROBLEM TO BE SOLVED: To improve profitability by suppressing an exciting rush current of a transformer for a converter or a linkage transformer and eliminating an excess overload capacity.;SOLUTION: A method for exciting the transformer in a power supply system having a plurality of power converters connected to a common bus via the transformer for the power converters to supply power to the power system from the bus via the transformer for the converters comprises a step of exciting the transformer for the converter and the linkage transformer connected via one power converter from a low voltage gradually up to a rated voltage.;COPYRIGHT: (C)2003,JPO
