Abstract

PURPOSE:To effectively reduce the unequilibrating component of the output current of one phase in an inverter by controlling the inverter of other phase together with the inverter of the corresponding phase on the basis of the unequibrating component existing in the one phase. CONSTITUTION:A DC voltage DC is converted to voltages EU-EW corresponding to the first to the third phases of 3-phase alternating currents via inverters 1-1- 1-3 and is then supplied through filters 2-1-2-3 to output lines 3-1-3-3 respectively. The currents IU-IW flowing through the output lines 3-1-3-3 are detected by current transformers 6-1-6-3 and are inputted through sensors 7-1-7-3 to respective control circuits 8-1-8-3, which detect the unequilibrating components existing in the inputted output currents IU-IW to produce compensation signals to the inverters 1-1-1-3 respectively.
