ABSTRACT:
This application describes a number of novel advanced piezoelectric ceramic power switching devices which are mounted within protective gastight enclosures that are either evacuated to a high degree of vacuum or filled with an inert gas protective atmosphere. The devices thus constructed are capable of operating over a range of load voltages extending from about 100 volts to 5000 volts or more with corresponding currents of from a few amperes to hundreds of amperes and wherein it is possible to provide a number of such structures in a single common protective gastight enclosure. For certain circuit applications the devices thus constructed have unpoled portions on which are mounted either passive circuit components such as resistors, capacitors and the like or active semiconductor devices all interconnected in circuit relationship with each other and the switching devices by using printed circuit or integrated circuit fabrication techniques. In these devices, stray circuit impedances whether capacitive, inductive or resistive in nature can be reduced to an absolute minimum by appropriate designs. Such complementary circuit components and active semiconductor devices can be, if desired, mounted within the common protective enclosures in close proximity to the piezoceramic switching devices to which they are connected, or alternatively may be mounted exteriorly of the protective enclosures.
