Abstract

Patente de Invenção: <B>"PROCESSO PARA O COMANDO DE PELO MENOS UM ELEMENTO DE AJUSTE CAPACITIVO"<D>. Processo para o comando de pelo menos um elemento de ajuste capacitivo, onde a partir da quantidade de carga (<30>Q) conduzida ao elemento de ajuste e da tensão de elemento de ajuste (Up) aplicada no elemento de ajuste após o término do procedimento de carga é calculada a capacitância de elemento de ajuste Cp = <30>Q/Up e, a partir destes valores é calculada a energia (E~ real~)= 0,5*Cp*Up² = 0,5*<30>Q*Up conduzida ao elemento de ajuste durante o procedimento de carga e que a tensão de carga (U~ L~ = U~ C1~ + U~ C2~) é regulada de tal forma, que a energia (E~ real~) suprida corresponde a um valor nominal (E~ nominal~) preestabelecido.
