Abstract

a presente invenção refere-se ao controle digital sincronizado de uma fonte de alimentação de soldagem. a sincronização pode ser com base nos pulsos de porta do inversor da fonte de alimentação de soldagem. pela sincronização nos pulsos de porta do inversor, as operações de amostragem, operações de coleta de dados, operações de processamento de dados, e outras funções de controle podem ocorrer em períodos vantajosos. em particular, essas operações do sistema podem ocorrer em períodos diferentes dos períodos de ligamento do inversor, melhorando assim a confiabilidade e a integridade das operações do sistema sincronizado.
