Summary :

This paper deals with a method for designing the driving circuit of an electroluminescent (EL) element whose power consumption is lower and the deviation of output voltage is smaller even when the EL element is replaced with another of a different shape. In this driving circuit, an AC voltage raised by a step-up transformer is supplied to the EL element. The oscillation conditions in the orthodox driving circuits were theoretically analyzed, and a new driving circuit which incorporates these characteristics is proposed. A new prototype driving circuit taking the resonance characteristics between the capacitance of the element and the inductance of the transformer into consideration was made. In the experiment, an inorganic AC EL cable-type element was used as the load of the driving circuit as its impedance can be easily adjusted by changing its length. In comparison with orthodox circuits, the power consumption was lower and the changes in the output voltage were smaller in the new prototype circuit even when the changes in the impedance were large.
