Abstract

"INVERSOR DE VOLTAGEM ESTáTICA SEM TRANSFORMADOR PARA SISTEMAS DE BATERIA". A presente invenção refere-se a um inversor estático para uma bateria de fontes de corrente elementares ou células eletricamente em série e um número N de tomadas de voltagem intermediárias ao longo da cadeia de fontes de corrente CC elementares, onde o número de células elementares compreendidas entre uma tomada intermediária e uma outra tomada intermediária adjacente a ela ou um terminal de extremidade da referida cadeia é proporcional à amplitude no respectivo intervalo de fase de um número N de fases de discretização da forma de onda da voltagem Ac a ser extraída em um quadrante; é implementado pela disposição de: um número N de chaves de potência, cada uma se conectando a uma respectiva tomada intermediária e um primeiro terminal de extremidade de uma primeira polaridade da referida cadeia de células elementares em série a um nó de circuito comum da referida primeira polaridade; um estágio de ponte de saída constituído por pelo menos quatro chaves de potência controladas em pares, para comutação dos percursos de corrente através do estágio de ponte, tendo um primeiro par de nós acoplados ao referido nó de circuito comum da referida primeira pluralidade e ao outro terminal de extremidade de polaridade oposta à referida primeira polaridade da referida cadeia de células elementares, respectivamente, e um segundo par de nós constituindo uma saída CA; e um circuito de controle que ativa, de forma seq³encial e cíclica, de uma maneira contínua, uma chave no tempo das referidas N chaves; cada uma para um intervalo de fase de 1/(4N) vezes o período da referida saída CA, e alternadamente ativando aos pares as referidas quatro chaves de potência do referido estágio de ponte de saída a cada metade de um período.
