Abstract

"MéTODOS E DISPOSITIVOS PARA A CONVERSãO DE ENERGIA DO CONTROLE DE PASSO". Um método para alimentar um sistema de comando de motor de passo (400) para ao menos um motor de passo de corrente contínua (410) de uma turbina eólica (100) inclui retificar a tensão empregando um circuito em ponte (402) para assim alimentar uma tensão de link DC para uma ponte (404) compreendendo dispositivos ativos de chaveamento (406), e utilizar ao menos um capacitor de link (408) para reduzir as variações na tensão de link DC e agir como um reservatório de energia e como uma fonte para o motor ou motores de passo DC (410).
