METHOD AND CONTROL DEVICE FOR PROTECTION TIME SETTING IN AN ELECTRIC DRIVE SYSTEM |
摘要 |
The invention relates to a control device (12) for actuating a pulse-controlled converter of an electric drive system, having: an open-loop/closed-loop control circuit (12a) which is configured to generate pulse-width-modulated actuation signals for switching devices of the pulse-controlled converter; a fault logic circuit (12b) which can detect fault states in the drive system and which is configured to select a switching state or a sequence of switching states for the switching devices of the pulse-controlled converter which are assigned to the corresponding fault state; and a protection circuit (12c) which is embodied in hardware and which comprises a signal delay device (15), which is configured to delay the actuation signals in order to implement a minimum protection time, and a locking device (16a, 16b) which is configured to lock two complementary switching devices of a bridge branch of the pulse-controlled converter with respect to one another. |
