Abstract

Patente de Invenção: <B>"SISTEMAS DE SUPRIMENTO DE ENERGIA ININTERRUPTOS, REGULADORES DE VOLTAGEM E MéTODOS DE OPERAçãO QUE EMPREGAM CIRCUITOS DE TRANSFORMADOR FERRORRESONANTES"<D>. Um sistema de suprimento de energia ininterrupto para produzir uma voltagem CA de pelo menos um dentre uma fonte de energia de CD, ou uma fonte de energia CA, inclui um terminal de entrada configurado para receber uma voltagem CA a partir de uma fonte de energia CA e um inversor operativo para produzir uma voltagem CA em uma sua saída a partir de uma fonte de energia CD. Um circuito transformador ferrossonante inclui um transformador que tem um enrolamento de entrada, um enrolamento de saída e um terceiro enrolamento que forma parte de um circuito ressonante que produz saturação no enrolamento em tal enrolamento de saída quando uma voltagem CA no enrolamento de entrada exceder uma amplitude predeterminada. Um circuito de controle de entrada de transformador é acoplado ao terminal de entrada e à saída do inversor e é operativo para acoplar pelo menos um terminal de entrada e a saída do inversor ao enrolamento de entrada. O circuito de controle de entrada de transformador acopla variavelmente o terminal de entrada ao enrolamento de entrada que responde pelo menos à voltagem no terminal de entrada, uma corrente em tal enrolamento de saída, uma voltagem no enrolamento de saída e uma corrente no terminal de entrada. Também são descritos os reguladores de voltagem e os métodos relacionados.
