Abstract

"CONVERSOR DE CC-EM-CC, E PROCESSO PARA CONTROLAR UMA SEGUNDA TENSãO DE CC EMITIDA PELO MESMO". Um processo e um conjunto para regular a tensão de saída (V2) de um conversor de CC-em-CC (100). O conversor de CC-em-CC (100) compreende um dispositivo conversor (101) e um dispositivos regulador (102). O dispositivo conversor é alimentado por uma primeira tensão de CC (V1) do dispositivo regulador. A primeira tensão de CC (V1) é determinada por uma parte de realimentação (VDIV) da tensão de saída (V2) do dispositivo conversor e uma tensão de referência (VREF). A tensão de referência é derivada de um trem de pulsos (PT1). A tensão de saída (V2) depende tanto da primeira tensão de CC (V1) como do trem de pulsos (PT1). A tensão de saída (V2) do conversor de CC em CC é mantida constante sob carga variável e o nível de tensão de saída pode ser ajustado de uma maneira fácil e flexível pelo trem de pulsos.
