摘要

Driver control a direction (101) for controlling a driver operation of a power switch element (21, 22),comprising:a pulse generator (1), of the alternating current pulse to two outputs (a, b) in synchronism with an externally supplied signal outputs (back);a set of level converter circuits (2, 3, 8, 9) for level conversion of the respective output signals of the two outputs of the pulse generator (1); anda flip-flop (4), which in a function of from said one of the output signals of the set of level converter circuits (2, 3, 8, 9) and set in dependence on the other output signal is reset,characterized by the,that the pulse generator (1) a pulse train, the two pulses, of which the respective predetermined time intervals have, as a pulse to at least one of the two outputs, which emits.
