Title: VOLTAGE GENERATING DEVICE AND METHOD FOR OPERATING A VOLTAGE GENERATING DEVICE
Abstract:
The invention relates to a voltage generating device (100) having the following: - a mechanically drivable generator device (10) which is separately excited; wherein - an electric starting voltage of the generator device (10) can be rectified by means of a rectifier device (30); - the voltage generating device (100) can be regulated by means of a regulating device (40, 50); - a current regulating device (50) has a model (54) of an excitation coil of the generator device (10), and a model value of the electric excitation current (ierr) of the generator device (10) can be ascertained using the model (54); - the current regulating device (50) additionally has a correction element (55), by means of which the model value of the electric excitation current (ierr) can be corrected such that the model value of the electric excitation current better matches the actual value of the electric excitation current in a defined manner.
