    • The invention relates an electronic switch for switching on and off high AC voltage between two connecting terminals. The switch includes two series-connected MOS floating gate transistors (20, 30; 20′, 30′), that can block and establish the transmission path between the applied high AC voltage connecting terminals. A charge storage device (24, 27, 34, 37; 24′, 34′, 60) stores charges and is connected to each gate of the MOS transistors. Each charge storage device (24, 27, 34, 37; 24′, 34′, 60) is assigned a charge feeding device (40, 50; 50) for applying a predetermined quantity of charge to the charge storage device (24, 34; 24′, 34′), which corresponds to a first switching state, and for removing a predetermined quantity of charge from the charge storage device, which corresponds to a second switching state. In this way, very low energy sensor outputs control high power AC voltage applied to the connecting terminals. This switch has utility in the automotive and other industries.

    • A piezoelectric transformer driver circuit can employ low voltage transistors. By alternately turning ON and OFF switching transistors b 3 and 4 depending upon gate signals GA and GB, a primary side of a piezoelectric transformer 7 is driven, and a secondary side is connected to a load 8. Inductors 1 and 2 are provided corresponding to transistors 3 and 4 for supplying a power source to corresponding transistors. Capacitors 10 and 11 respectively connected to one of the electrode of the inductors 1 and 2, respectively. The transistor 12 is turned ON upon completion of ON/OFF operation of the transistors 3 and 4, and the capacitors 10 and 11 are situated the other electrode at the ground voltage. Upon completion of ON/OFF operation of the transistor, a surge voltage to be generated by the inductors 1 and 2 can be restricted to permit use of the low voltage transistor. Thus, the overall circuit can be compact and low cost.
