Abstract
A driver circuit for generating a sequence of pulses of a drive voltage from a supply voltage is described. The drive voltage is used for operating an electrical actuator, such as an electrical engine or machine. The driver circuit comprises means for providing an amplitude indication of an amplitude of the supply voltage, which is used for generating a first pulse of the sequence of pulses. Furthermore, the driver circuit comprises an integration unit configured to integrate the amplitude indication for a duration of the first pulse, thereby generating an integrated voltage. In addition, the driver circuit comprises a comparator configured to compare the integrated voltage with a reference voltage, thereby generating a comparator signal. Furthermore, the driver circuit comprises a control unit configured to terminate the first pulse in dependence of the comparator signal.
