IDEA #301UI9 Method and system for transformer control

A method to balance transformer flux among a plurality of transformers is disclosed. The plurality of transformers is connected to a plurality of converters, each transformer having an associated converter. The method comprises determining a reference flux value, measuring an actual flux value for each transformer, and developing a plurality of voltage command signals in relation to a plurality of variance values between the reference flux value and each actual flux value. In response to the voltage command signals being received at a modulator in signal communication with the plurality of converters, the method proceeds by generating a plurality of switching signals to reduce each of the variance values by making available the plurality of switching signals to each of the associated plurality of converters. https://app.acclaimip.com/pdf/-d_QUIYHpQk139A1YwelBV4prcmISYDuEz39tPg/US7327134B1
