发明名称 STEP-DOWN DEVICE
摘要 PURPOSE:To work all of electrical equipments normally and suppress power demand at the same time, by putting together peak voltage generated with a peak voltage generating transformer based on the output voltage of an unsaturated transformer, with the output voltage of the unsaturated transformer, by means of a transformer for putting together. CONSTITUTION:Incoming sine wave AC voltage E0 from a power system is stepped down to sine wave AC voltage E1 by an unsaturated transformer 10. The sine wave AC voltage E1 is fed to a peak voltage generating transformer 20, and peak voltage e2 is formed. The peak voltage e2 is put together with the sine wave AC voltage E1 via a putting-together transformer 30, and the output of voltage E2 is generated. Besides, the maximum value of the peak voltage e2 is set to be equal to the maximum value of the sine wave AC voltage E0.
