PURPOSE:To reduce the voltage fluctuation of a power source, by containing a timer circuit switching-controlled for a given time, in a control section, after the input of external signal is provided. CONSTITUTION:An inverter 6 is organized with a control section 1, a three phase switching element module 2, a DC power source 3, a timer circuit 4, and output terminals 5, and the output side of the control section 1 is connected to the module 2 and the input side is connected to the timer circuit 4, respectively. Besides, the input side of the module 2 is connected to the DC power source 3, and the output side is connected to the output terminals 5, respectively. The chopping of the DC power source 3 is performed by signal from the control section 1 through the module 2, and current is fed from the output terminals 5. Besides, after the input of timer start signal is provided, the output of working signal to the control section 1 is generated from the timer circuit 4 for a given time. Accordingly, while the input of said working signal to the control section 1 is provided, the module 2 is switching-controlled. |
