Abstract
Řečení se týká oblasti radiotechniky a je určen především pro zesílení výkonu signálu zvukové frekvence. Můstkový zesilovač s oohranou před přetížením obsahuje dva dvojčinné zesilovací stupně, z nichž každý je proveden na prvním a druhém tranzistoru různé struktury, v jejich okruhu posunu základny jeou zapojeny hradla a zdroj proudu. První tranzistor každého dvojčinného zesilovacího stupně je vybaven snímačem proudu, snímačem napětí, připojenými k řídicímu vstupu regulujícího prvku. První výstup regulujíoiho prvku je spojen se základnou prvního tranzistoru téhož dvojčinného zesilovacího stupně. Každý druhý výstup regulujícího prvku jednoho dvojčinného zesilovacího stupně je spojen se základnou druhého tranzistoru druhého dvojčinného zesilovacího stupně.The invention relates to the field of radio engineering and is intended primarily for amplifying the power of an audio frequency signal. A bridge amplifier with overload protection comprises two double-acting amplifier stages, each of which is made on a first and second transistor of a different structure, and in their base shift circuit the gates and a current source are connected. The first transistor of each double-acting amplifier stage is equipped with a current sensor, a voltage sensor, connected to the control input of the regulating element. The first output of the regulating element is connected to the base of the first transistor of the same double-acting amplifier stage. Each second output of the regulating element of one double-acting amplifier stage is connected to the base of the second transistor of the second double-acting amplifier stage.
