QUASI-RESONANCE CONSTANT VOLTAGE CONVERTER WITH LOW PULSATIONS OF OUTPUT VOLTAGE DURING OPERATION IN CONDITIONS OF HIGH NEGATIVE TEMPERATURES

摘要

FIELD: electrical engineering.;SUBSTANCE: invention relates to conversion equipment and can be used as a source of supply of LED lamps from AC rectifier, in operation under conditions of high negative ambient temperatures.;EFFECT: technical result consists in reduction of output ripple of output voltage/current transducer pulsation at negative temperature due to adjustment of voltage on transistor of current stabilizer, compensating pulsation, in compliance with ambient temperature, and use of increased power allocated on transistor of current stabilizer, for heating of output electrolytic capacitor.;1 cl, 6 dwg
