Abstract
Fuente de alimentación de modo conmutado con un transmisor (T180), la cual presenta un arrollamiento primario (W1), un arrollamiento auxiliar (W2) y al menos un arrollamiento secundario (W3), donde el arrollamiento primario está en serie con un transistor de conmutación (V160) en una tensión continua de entrada (U, , ) y aguas abajo del arrollamiento secundario están conectados un rectificador (Glr) y un condensador de carga (CL), con un circuito de activación (ASA), para cuya alimentación de corriente están previstos un rectificador auxiliar (V170), conectado aguas abajo del arrollamiento auxiliar, y un condensador (C170), y que proporciona para el conmutador impulsos de arranque de frecuencia fija, con un sensor de corriente (R161) para la corriente a través del arrollamiento primario (W1), con al menos un amplificador de regulación (RV) para la comparación de la tensión de salida (U)S y/o de la corriente de salida (IS) con un valor de referencia Uref ) ajustable, donde como señal de ajuste (US) para el circuito de activación se alimentan la señal de salida de al menos un amplificador de regulación (RV), así como la señal de salida (UL) del sensor de corriente para influir sobre la relación de muestreo del conmutador, caracterizada porque el circuito de activación (ASA) posee un multivibrador (V121, V130) astable de frecuencia fija, una señal de salida del multivibrador es alimentada a través de una fase de separación (V131) a la entrada de una fuente de corriente controlada (V140, V143, T140), y la salida de la fuente de corriente está conectada con el electrodo de control de un transistor de conmutación (V160) en el circuito de corriente primaria, para conectar el transistor de conmutación (V160) con un primer flanco de la señal de salida del multivibrador, el electrodo de control del transistor de conmutación se puede colocar en un potencial de desconexión a través de un tiristor controlado (V142, V141), siendo alimentada al tiristor, como señal de control, por una parte, la señal de ajuste (US, ) y, por otra parte, la señal de salida (UI) del sensor de corriente (R161), y siendo alimentados al tiristor, como impulsos de extinción, respectivamente, los segundos flancos de la señal de salida del multivibrador.
