<p>The arrangement (300) has an active electronic switch arrangement e.g. active rectifier and active pulse inverter, for regulating voltage, which is induced by a magnetic field generated by an electric machine, if excitation current (178) is zero and induced voltage is greater than a power supply (204) of an energy network. The electric machine comprises a permanent magnet and field winding that guides the excitation current. The electronic switch arrangement is connected with a conductor and energy network. An independent claim is also included for a method for operating an electric machine.</p> |
