Abstract

"MéTODO, CIRCUITO ADAPTADOR E ADAPTADOR PARA CONTROLAR UMA PONTE DE INVERSOR DE MúLTIPLOS NìVEIS COM UM CONTROLADOR DE MOTOR DE INDUçãO DE DOIS NìVEIS E, SISTEMA ACIONADOR DE MOTOR DE INDUçãO PARA ACIONAR UM MOTOR TRIFáSICO". Trata-se de um método e um circuito que permite que os controladores fora da prateleira destinados para o uso com uma ponte de inversor de acionador de Corrente Alternada (1920) para acionar pontes de inversor com três ou mais níveis. Os sinais de um controlador de motor de indução comum ou de um controlador de motor de indução de dois níveis (2200) são utilizados para acionar doze ou mais comutadores de uma ponte de inversor de três ou mais níveis (1920), tais como são utilizados em aplicações de média e alta voltagem. A seq³ência apropriada e a temporização da comutação para a ponte de inversor de três ou mais níveis são baseadas em parte na saída dos moduladores de seis pulsos ou então na saída do dispositivo de controle de fluxo e torque, ou do dispositivo de controle de voltagem (2210), do controlador de dois níveis (2200).
