Abstract :
For promoting the application of electroluminescent (EL) devices, a thin-plate-typ DC-AC converter is required. For this purpose, a novel type of power supply that uses switched capacitor (SC) transformers is presented. This power supply generates on AC voltage of more than 100 V with several hundred hertz by using two types of SC transformers. This scheme has the following advantages: (1) it operates on a low battery voltage, (2) it realizes a very large transformer ratio, (3) it is capable of realization in an IC form as a thin plate type power supply that is capable of being unified onto the back of an EL device, and (4) it generates a sinusoidal voltage in a novel way by selection of voltages. The circuit configurations, operations, and basic experimental results are presented
