Abstract

MÉTODO DE CONTROLE DE ALIMENTAÇÃO E SISTEMA DE ALIMENTAÇÃO. A presente invenção refere-se a método de controle de alimentação que compreende: adquirir informações de tensão de cada circuito de entrada; gerar um primeiro sinal de controle de acordo com as informações de tensão e um valor de tensão de barramento; converter, de acordo com o primeiro sinal de controle, uma tensão de cada circuito de entrada em uma tensão de barramento; adquirir informações de carga; gerar um segundo sinal de controle de acordo com as informações de carga e o valor de tensão de barramento; converter a tensão de barramento em uma tensão de carga de acordo com o segundo sinal de controle; e emitir a tensão de carga. A disposição acima suporta múltiplas tensões de entrada e/ou múltiplas tensões de saída. A invenção emprega gerenciamento unificado para melhorar a flexibilidade de fonte de alimentação e aperfeiçoar a eficiência de gerenciamento de alimentação. Também provido está um sistema de alimentação capaz de implementar o método de controle de alimentação acima.
