  • Patent number: 10755881
    Abstract: An example circuit arrangement and method for actuating an electromagnetic drive system for electromechanical devices is disclosed, the example circuit arrangement including a mechanically locked end position, a control voltage source, a regulating and control circuit, a drive system, a transformer, a rectifier bridge a smoothing capacitor, and a main switching transistor, by means of which the drive system can be controlled in a characteristic pulse tracking system. In the example, the main switching transistor is connected in series to a primary branch of the transformer, the transformer is connected to the supply voltage, and the secondary winding of the transformer supplies the rectifier bridge, the output DC voltage of which is smoothed by the smoothing capacitor and added to the voltage of the control voltage source so as to result in a DC voltage feed having a chronological supply progression.
