Abstract
FUENTE DE ALIMENTACION CONMUTADA CON LIMITACION DE CORRIENTE DE CORTOCIRCUITO. FUENTE DE ALIMENTACION CONMUTADA EN LA QUE SE REALIZA UN CONTROL EN MODO CORRIENTE Y QUE INCLUYE UN AMPLIFICADOR DE ERROR (1) Y UN OSCILADOR (2). DICHA FUENTE DE ALIMENTACION COMPRENDE ADEMAS UN AMPLIFICADOR DIFERENCIAL (3) CONECTADO AL OSCILADOR (2) PARA MODIFICAR LA FRECUENCIA DE OSCILACION EN CASO DE CORTOCIRCUITO A SU SALIDA. EL AMPLIFICADOR DIFERENCIAL (3) SE ALIMENTA CON LA SEÑAL DE SALIDA (VO) DEL AMPLIFICADOR DE ERROR (1). ESTA SEÑAL DE SALIDA (VO) DEL AMPLIFICADOR DE ERROR (1) ES PROPORCIONAL A LA CORRIENTE DE SALIDA ENTREGADA POR LA FUENTE DE ALIMENTACION DE FORMA QUE CUANDO SUPERA UN DETERMINADO VALOR, LA FRECUENCIA DEL OSCILADOR (2) SE REDUCE PARA LIMITAR LA CORRIENTE DE CORTOCIRCUITO A UN VALOR MAS PEQUEÑO.
