Abstract
A method for controlling a semiconductor bridge of an electrically operable motor, the semiconductor bridge being controlled depending on a pulse width modulation signal by a first controllable semiconductor switch and a separate second controllable semiconductor switch for supplying the electrically operable motor with electrical energy, a ramp signal with a predeterminable ramp slope for controlling one of the two controllable semiconductor switches being generated by a ramp generator, depending on the pulse width modulation signal. The invention also relates to a control device and to an arrangement.
