Abstract

método, aparelho e sistema de controle de inversor de cadeia e meio de armazenamento. este pedido divulga um método, aparelho e sistema de controle de inversor de cadeia, e um meio de armazenamento, e pertence ao campo das tecnologias fotovoltaicas. o método inclui: em um processo de realização de varredura de curva iv nos um ou mais primeiros circuitos elevadores de corrente contínua/corrente contínua, controlar uma mudança de uma tensão de saída dos um ou mais segundos circuitos elevadores de corrente contínua/corrente contínua nos quais varredura de curva iv não precisa ser realizada, em que uma tendência de mudança da tensão de saída e uma tendência de mudança de uma tensão de entrada dos um ou mais primeiros circuitos elevadores de corrente contínua/corrente contínua nos quais varredura de curva iv é realizada apresentam uma relação não estritamente monotonicamente crescente. portanto, para o circuito elevador de corrente contínua/corrente contínua no qual varredura de curva iv é realizada, uma diferença de tensão entre as duas extremidades do circuito elevador de corrente contínua/corrente contínua nem sempre está em um estado relativamente alto, de modo que uma corrente de ondulação em um indutor de entrada no circuito elevador de corrente contínua/corrente contínua pode ser reduzida. dessa forma, o seguinte caso pode ser evitado: proteção de sobrecorrente é desencadeada no circuito elevador de corrente contínua/corrente contínua devido à corrente de ondulação excessivamente grande no indutor de entrada.
