Abstract

UN CIRCUITO DE SUMINISTRO DE ENERGIA PARA SUMINISTRAR CORRIENTE DE CARGA A UNA CARGA COMPRENDE UN CONMUTADOR DE CORRIENTE CONECTADO SOBRE EL LADO POTENCIAL ALTO DE UNA CARGA. CON EL FIN DE DETECTAR UNA CONDICION DE CORRIENTE, TAL COMO UNA CONDICION SE SOBRECORRIENTE EN LA CARGA, UNA UN CIRCUITO DE DETECCION DE CORRIENTE COOPERA PREFERENTEMENTE CON EL CONMUTADOR DE CORRIENTE , TAL CONMUTADOR COMPRENDE UN DISPOSITIVO MULTICELULAR CON UNA PLURALIDAD DE TERMINALES. TALES TERMINALES COMPRENDE UN TERMINAL DE CORRIENTE PRINCIPAL CONECTADO A UNA FUENTE DE ALTO POTENCIAL, UN SEGUNDO TERMINAL DE CORRIENTE PRINCIPAL QUE CONECTA UNA MAYORIA DE CELULAS DE DISPOSITIVO A LA CARGA, UN PRIMER TERMINAL AUXILIAR CONECTADO A UN EXTREMO A UNA MINORIA DE CELULAS DE DISPOSITIVO DE MANERA A PROPORCIONAR CORRIENTE GENERALMENTE PROPORCIONAL A LA CORRIENTE DE DISPOSITIVO PRINCIPAL, Y UN SEGUNDO TERMINAL AUXILIAR CONECTADO EN UN EXTREMO A UNA MAYORIA DE CELULAS DE DISPOSITIVO. EL CIRCUITO DE DETECCION DE CORRIENTE COMPRENDE PREFERENTEMENTE UNA RAMA CONECTADA ENTRE EL PRIMER TERMINAL AUXILIAR Y TIERRA Y QUE COMPRENDE, EN CIRCUITO EN SERIE, UNA RESISTENCIA DE CONVERSION CORRIENTE A TENSION QUE PREVE UNA TENSION EN UN EXTREMO APROXIMADAMENTE PROPORCIONAL A LA CORRIENTE DE DISPOSITIVO PRINCIPAL Y UN DISPOSITIVO DE TRANSIMPEDANCIA CONTROLADAS POR SEÑAL DE POLARIZACION,Y OTRA RAMA CONECTADA ENTRE EL SEGUNDO TERMINAL AUXILIAR Y TIERRA Y QUE PREVE UNA SEÑAL DE POLARIZACION PARA EL DISPOSITIVO DE TRANSIMPEDANCIA, LA PRIMERA RAMA COMPRENDE AL MENOS DOS TRANSISTORES Y UNA RESISTENCIA CONECTADOS EN SERIE ENTRE UN TERMINAL DE DETECCION DE CORRIENTE DEL MOSFET Y UN POTENCIAL DE REFERENCIA. LA SEGUNDA RAMA TAMBIEN COMPRENDE AL MENOS DOS TRANSISTORES CONECTADOS EN SERIE ENTRE UN TERMINAL DEL MOSFET Y EL POTENCIAL DE REFERENCIA. LOS TRANSISTORES ESTAN CONECTADOS TRANSVERSALMENTE ENTRE RAMAS Y PREVEN UN ESPEJO DE CORRIENTE INVERTIDA Y UN ESPEJO DE CORRIENTE. EL QUINTO Y EL SEXTO TRANSISTOR TAMBIEN PUEDEN SER INCLUIDOS COMO PARTE DEL CIRCUITO DE DETECCION DE CORRIENTE.
