Abstract:
A generator system for a motor vehicle comprising:an asynchronous generator; and a converter to produce converter output voltages from a direct current source to form a three-phase system to produce a rotating field suitable for a generator function, to thereby form rotating fields suitable for the generator function, wherein the converter output voltages have a CO frequency that is changeable in dependence on a range of rotational speed of the generator, and wherein a voltage curve of the converter output voltages can be broken down into a primary component with a sinusoidal voltage curve of the CO frequency and at least one additional secondary component with a sinusoidal voltage curve with an odd-numbered multiple of the CO frequency, and wherein the components are weighted in such a manner that an amplitude of the primary component is greater than an amplitude of the voltage curve of the converter output voltages, to provide a voltage magnification.
