Head Afanas'yev P.V., Registration Date 11-06-2001 Organization Ukrainian Scientific Research Institute of Radio and Television Radio and Television popup.description2 The objects of research are wireline broadcasting amplifiers and power supplie with transformerless input. The goal of the work is the development of output module for wireline broadcasting 500 Wt amplifier, based on the modern basis with increased efficiency and reliability. The method of research is the control of voltage, which feeds the output cascade of wireline broadcasting amplifier, with dependence on input rule of amplified signal. The analysis of efficiency increasing methods for output cascades of existing wireline broadcasting amplifiers is carries out, the recommendations on choosing and using the modern foreign basis are given. The schematic approaches of power supply with transformerless input up to 1,5 kWt, high-speed voltage regulator, amplifier output cascade are worked out. The developed module provides output power of 500 Wt at the output parameters, corresponding to given requirements. Range of application: wireline broadcasting amplifiers.
