Method and apparatus to operate an intermediate circuit converter with current rise limitation |
摘要 |
To assure the commutatibility of an intermediate circuit converter with an impressed intermediate circuit d.c. current it is sufficient to limit the rate of rise of the intermediate circuit current under operating conditions to the product f*. i* from the current and frequency of the converter. A rate of rise limited in such a fashion to a maximum value reflecting operating conditions can be preset to a rate of change limiter using a rate of rise limiting controller to which the preset maximum value as well as the rate of rise of the control value for the intermediate circuit current itself has been preset. For that purpose a current controller, whose output signal are connected to suitable control values, assures an immediate control of the intermediate circuit current to the current reference value which has been limited in its rate of rise.
