Abstract

The main aim of this work was to determine the most efficient way for minimization of power loss in the horizontal deflection output stage transistor. In the monitors and TV receivers with the kinescopes of colored image in the final stage of horizontal deflection the high-voltage bipolar transistors of large power commonly are used. Because of their small factor of amplification base current must be comparatively large and they will change according to the complex law. For the formation of base current the transformer, suitable only for the specific set of elements, commonly is used. It is shown that the losses of switching can be decreased and even when the value of the voltage of supply of penultimate cascade. The simulation and experiment results are given. Ill. 6, bibl. 5 (in English; summaries in English, Russian and Lithuanian).
