Abstract

PURPOSE:To prevent a lighting device from flickering, by making the characteristic of a voltage fluctuation suppressing load connected to a fluctuation load for repeating conduction quiescence in parallel with each other, almost equal to the characteristic of the fluctuation load, and by making and breaking the fluctuation load and the voltage fluctuation suppressing load in opposite phase. CONSTITUTION:To a main circuit 1, the fluctuation load 2 of the hard fluctuating load of a seam welder or the like is connected, and a voltage fluctuation suppressing load 5 is connected in parallel with the load 2. The fluctuation suppressing load 5 and the fluctuation load 2 are composed so that the load characteristics may be made almost equal to each other, and by the output of a controller 8, the switches 4, 7 of thyristors are alternately turned ON/OFF in opposite phase. Besides, to the main circuit 1, a reactive power compensator 10 is connected, and the reactive power of the main circuit 1 is detected by a CT, and according to its value, a phase advancing capacitor 13 is made in succession. As a result, the fluctuation of the line voltage of the other load connected to the main circuit 1 is effectively suppressed. This suppressor is suitable for preventing a lighting device from flickering.
