Abstract

circuito controlador. um circuito controlador (1) para controlar uma carga capacitiva (2) com um pulso de controle tendo um tempo de subida, um período de tensão predeterminado e um tempo de queda. o circuito controlador (1) compreende uma indutância (6), comutadores (10, 11, 12), e um transformador (8) tendo um lado primário (8) e lado secundário (9). os comutadores (10, 11, 12) são controlados por um controlador (13) para carregador a indutância (6) a paritr de uma fonte de alimentação (4), e, quando a carga capacitiva (2) deve ser acionada, habilitar um caminho de carga a partir da indutância (6) para a carga capacitiva (2) durante o tempo de subida, desabilitar o caminho de carga durante o período de tensão de pico constante e habilitar um caminho de descarga através do lado primário (8) do transformador (7) durante o tempo de queda. à medida que a carga capacitiva (2) descarga através do lado primário (8) do transformador (7), carga é induzida no lado secundário (9) do transformador (7) e é usada para carregar a indutância (6),assim economizando energia e habilitando uma fonte de alimentação de tensão mais baixa a ser utilizada.
