Abstract
A controller for AC power converter having an LC filter connected to a load, can suppress fluctuation of the output bus voltage against disturbance, particularly against fluctuation of load current by calculating a capacitor current command from a voltage feed back value and then adding an interference component caused by a reactor and a capacitor to the voltage command of the AC power converter.
