Abstract

MÉTODO E APARELHO DE CONTROLE DE CARGA PARA CONVERSOR HÍBRIDO. O Pedido fornece um método de controle de carga para um conversor híbrido, compreendendo: realizar o primeiro desvio em submódulos full-bridge, em todos os braços de ponte, um a um, até que um primeiro número de desvio alcance um primeiro valor estabelecido ou uma tensão média dos submódulos full-bridge for igual àquela dos submódulos half-bridge; quando o número do primeiro desvio alcança o primeiro valor estabelecido e a tensão média dos submódulos full-bridge não for igual àquela dos submódulos half-bridge, realizar o segundo desvio nos submódulos half-bridge em todos os braços de ponte um a um, até que um número do segundo desvio alcance um segundo valor estabelecido ou a tensão média dos submódulos full-bridge for igual àquela dos submódulos half-bridge; ajustar de forma dinâmica o número do primeiro desvio e o número do segundo desvio de acordo com a tensão média dos submódulos full-bridge, a tensão média dos submódulos half-bridge e uma tensão de carga nominal; e realizar o desvio de acordo com o número de primeiro desvio e o número de segundo desvio dinamicamente ajustados, até que ambas a tensão média dos submódulos full-bridge e a tensão média dos submódulos half-bridge alcancem a tensão nominal. Desta forma, todos os submódulos podem alcançar suavemente a tensão nominal.
