Abstract

UNA IMPULSION PARA UN PROBADOR (13) DE FACOEMULSION INCLUYE UN CIRCUITO (15) DE IMPULSION PARA SUMINISTRAR POTENCIA ELECTRICA AL PROBADOR (13), CIRCUITERIA (29) PARA DETECTAR LA POTENCIA ELECTRICA SUMINISTRADA POR EL CIRCUITO (15) DE IMPULSION PARA EL PROBADOR (13) Y PARA SUMINISTRAR SEÑALES ELECTRICAS, INDICADORAS DE LA MAGNITUD DE LA POTENCIA ELECTRICA SUMINISTRADA. UN DISPOSITIVO (21) DE ENTRADA OPERABLE MANUALMENTE PROVEE UNA SEÑAL INDICADORA DEL NIVEL DE POTENCIA DEL TRANSDUCTOR DESEADA POR EL USUARIO DEL PROBADOR (13). UN CIRCUITO DE CONTROL RESPONDE A LA SEÑAL INDICADORA DEL NIVEL DE POTENCIA DESEADO EN EL TRANSDUCTOR Y A LAS SEÑALES INDICADORAS DE LA MAGNITUD DE LA POTENCIA ELECTRICA SUMINISTRADA PARA PROVEER SEÑALES DE CONTROL AL CIRCUITO (15) DE IMPULSION PARA CONTROLAR LA POTENCIA APLICADA DE UNA MANERA EFICIENTE. EL CIRCUITO DE IMPULSION (15) INCLUYE UN CONMUTADOR (31) DE SISTEMA JERARQUICO, DE RESPUESTA A AL MENOS UNO DE LAS SEÑALES DE CONTROL, PARA APLICAR POTENCIA EN FORMA DEONDA CUADRADA, Y UN REGULADOR (27) DE CONMUTACION PARA SUMINISTRAR UN SUMINISTRO DE TENSION AL CONMUTADOR (31) DE SISTEMA JERARQUICO. EL CONMUTADOR (31) JERARQUICO TIENE CIRCUITERIA ASOCIADA CON EL, LA CUAL RESPONDE A UNA DE LAS SEÑALES DE CONTROL PARA VARIAR INICIALMENTE LA FRECUENCIA DE LA ONDA CUADRADA. EL REGULADOR (27) RESPONDE A UNA SEGUNDA SEÑAL (A) DE CONTROL DEL CIRCUITO DE CONTROL PARA VARIAR LA TENSION SUMINISTRADA POR EL REGULADOR (27) PARA EL CONMUTADOR (31) JERARQUICO, PARA CONTROLAR LA AMPLITUD DE LA ONDA CUADRADA. LA NATURALEZA DE LA CONMUTACION DE ESTE SISTEMA MINIMIZA SUSTANCIALMENTE EL CONSUMO DE POTENCIA DEL CIRCUITO (15) DE IMPULSION CUANDO SE COMPARA CON TECNICAS CONVENCIONALES.
