Abstract
The invention relates to an arrangement ( ) and a method for adjusting the slope times of one or more drivers ( ) in such a way that the adjustment is essentially independent of external conditions. The invention also relates to a driver circuit. The arrangement ( ) is provided with a device ( ) for detecting the time history of an output voltage that is output and supplied to a load ( ) by means of the driver/s ( ). The measured time values are converted into an output voltage value in a device ( ) for converting the measured time history of the output voltage. Moreover, a device ( ) for generating a reference voltage value is provided. The device ( ) is connected to a device ( ) for predetermining a desired slope time for the driver/s ( ), whereby the slope time is essentially independent of external conditions. A system pulse can be partitioned into differently long rectangular pulses in the device ( ) in such a way that the user of the arrangement ( ) can select from the group of the rectangular pulses which match certain slope times respectively. The output voltage value and the reference voltage value are compared in a comparing device ( ) that is also connected to the driver/s ( ) in such a way that the driver/s ( ) can be readjusted thereby.
