Abstract

EL PRESENTE INVENTO SE REFIERE A UN INTERRUPTOR DE POTENCIA (T115,T5) QUE CONSTA DE AL MENOS UNA ETAPA DE POTENCIA DE TRANSISTOR BIPOLAR (T5) Y UN CIRCUITO DE CONTROL DE ESTA ETAPA, CONSTANDO EL CIRCUITO DE CONTROL DE UNOS PRIMEROS ELEMENTOS DE POLARIZACION PARA APLICAR A DICHA ETAPA, DURANTE UNOS PRIMEROS INTERVALOS DE TIEMPO (T3), UNA POLARIZACION DIRECTA, ASI COMO UNOS SEGUNDOS ELEMENTOS DE POLARIZACION PARA APLICAR A DICHA ETAPA, DURANTE UNOS SEGUNDOS INTERVALOS DE TIEMPO (T2,T4), UNA POLARIZACION INVERSA DESTINADA A EVITAR QUE SE ACUMULEN CARGAS EN EL TRANSISTOR MIENTRAS ESTE ESTA EXPUESTO A UNA TENSION INVERSA. SEGUN EL INVENTO, LOS PRIMEROS ELEMENTOS DE POLARIZACION CONSTAN DE UN PRIMER CONDENSADOR (C108) Y UN PRIMER CIRCUITO DE CONMUTACION (D120,T113) PARA CARGAR SELECTIVAMENTE EL PRIMER CONDENSADOR MEDAINTE UNA FUENTE DE TENSION CONTINUA (VP) FUERA DE LOS PRIMEROS INTERVALOS DE TIEMPO Y DESCARGAR EL PRIMER CONDENSADOR EN UNA ENTRADA DE CONTROL (T115,G) DE DICHA ETAPA, Y LOS SEGUNDOS ELEMENTOS DE POLARIZACION CONSTAN DE UN SEGUNDO CONDENSADOR (C107) Y UN SEGUNDO CIRCUITO DE CONMUTACION (D119,D123,T113,T114) PARA CARGAR DE FORMA SELECTIVA EL SEGUNDO CONDENSADOR MEDIANTE LA FUENTE DE TENSION FUERA DE LOS SEGUNDOS INTERVALOS DE TIEMPO Y DESCARGAR EL SEGUNDO CONDENSADOR EN LA ENTRADA DE CONTROL.
