摘要：A driver circuit for generating a sequence of pulses of a drive voltage from asupply 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 providingan 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 circuitcomprises an integration unit configured to integrate the amplitude indication for aduration of the first pulse, thereby generating an integrated voltage. In addition, thedriver circuit comprises a comparator configured to compare the integrated voltage witha reference voltage, thereby generating a comparator signal. Furthermore, the drivercircuit comprises a control unit configured to terminate the first pulse in dependence ofthe comparator signal.
