DEVELOPMENT OF EFFECTIVE AND QUICK-ACTION OSCILLATORS WITH PIEZO-ELECTRIC RESONATORS

The work covers the control systems of oscillators with piezo-electric resonators. The aim is to develop and investigate the procedures of designing oscillators with high quick-action and efficiency by a regulation of the electric power supplying the oscillators at keeping economic operation condition. The block diagrams and equivalent circuits of oscillators with high quick-action and efficiency have been proposed; the investigations of change character in their amplitude, frequency and time of tuning oscillations have been performed. A number of the new quick-acting and power-effective ultrasonic generators has been developed. The voltage sources manufactured on base of the oscillators with piezo-transformers have been introduced in the Centre "Ingener" (Moscow) and Research Institute of Polymers (t. Dzerzhinsk). The developments can be used in the enterprises possessing with work-out and investigations of the ultrasonic control-measurements devices and technological equipmentAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
