Abstract
SE DESCRIBE UN CIRCUITO DE ALIMENTACION DE CORRIENTE DE MODO CONMUTADO CON DOS ESTADOS, EN PARTICULAR UN ESTADO OPERATIVO Y UN ESTADO DE ESPERA, EN EL QUE EL VALOR DE UNA PRIMERA TENSION DE SALIDA ES CONSIDERABLEMENTE MENOR QUE EN EL ESTADO OPERATIVO, MIENTRAS QUE EL VALOR DE UNA SEGUNDA TENSION DE SALIDA ES SUSTANCIALMENTE EL MISMO. CON AYUDA DE UN CIRCUITO DETERMINADOR DE DURACION (TR7, TR8, R17, C12), QUE ES CONTROLADO POR UN CONMUTADOR (TR6) OPERATIVO DURANTE EL ESTADO DE ESPERA, SE MANTIENE UN MODO DE DESCARGA BRUSCA DE BAJA FRECUENCIA DURANTE ESTE ESTADO, SIENDO EL CONMUTADOR DE LA ALIMENTACION CONDUCTOR UN NUMERO CONSECUTIVO DE VECES Y SIENDO SUBSIGUIENTEMENTE NO CONDUCTOR UN PERIODO DADO.
