Application Number: JP,2022-091972
Category (FI): H02H7/06,H02P103:20,H02H7/00@G,H02P9/14
Stage: PROBLEM TO BE SOLVED: To suppress a voltage fluctuation rate with respect to a rated voltage in an AC power generator.SOLUTION: A voltage fluctuation suppressing device is installed in an AC power generator, and suppresses a voltage fluctuation by performing excitation control based on an output voltage. The voltage suppressing device includes a load current detection unit that detects a load current of each output terminal, an in-use output terminal identification unit that identifies an output terminal which is being used on the basis of detection performed by the load current detection unit, an inter-terminal voltage detection unit that detects a voltage between terminals including the output terminal identified by the in-use output terminal identification unit, and an excitation control unit that performs excitation control at an output voltage obtained from the inter-terminal voltage detected by the inter-terminal voltage detection unit.SELECTED DRAWING: Figure 1 (Grant)
