Abstract:
A high voltage switching device comprising:a translator type switch for switching a high voltage to at least one capacitive type output line and for providing a control signal; a switching transistor connected to said translator type switch for switching a low voltage to the at least one capacitive type output line based upon the control signal, the control signal having a first level to turn said switching transistor off when said translator type switch applies the high voltage to the at least one capacitive type output line, and having a second level to turn said switching transistor on so that the low voltage is applied to the at least one capacitive type output line; and a control circuit connected to said translator type switch and to said switching transistor for providing a control loop for controlling a drop in voltage of the control signal applied to said switching transistor based upon a drop in voltage on the at least one capacitive type output line from the high voltage to the low voltage.
