Pulse flank setting device for semiconductor switch controlling servo braking amplifier magnetic valve

摘要

The pulse flank setting device uses at least one feedback device (21,22) providing a signal in response to an alteration in the output value of the semiconductor switch (10), for correction of the control signal (11) for the switch, provided by discrete pulses. The switch (10) is provided by a MOSFET, supplied with the control signal (11) via a summation point receiving subtractive values from 2 feedback devices (21,22), respectively receiving the drain voltage and the source current of the switch.
