Abstract
In a method for providing a voltage for a load, e.g., for an inductor and/or coil of an electromagnetically actuable brake, e.g., of an electric motor, and device for carrying out the method, e.g., in a manner repeated over time, the positive half-wave of an, e.g., single-phase AC voltage is provided to the load in a pulse—with modulated manner starting from a first phase angle of the AC voltage, and in an unmodulated manner, e.g., and/or uncontrolled manner and/or directly, starting from a second phase angle.
