Abstract
Systems for parallel excitation for a synchronous machine are provided. Aspects include a rectification circuit coupled to an output of a permanent magnet generator, and an excitation winding connected to an output of the rectification circuit, a direct current (DC) power source connected between an output of the rectification circuit and the excitation winding, wherein the excitation winding supplies an excitation voltage to an excitation armature in a main generator during a during a plurality of operational modes, wherein the plurality of operational modes comprise a startup mode and a generator mode, wherein a DC excitation voltage is provided to the excitation windings by the DC power source during the startup mode, and wherein the DC excitation voltage is provided to the excitation windings by the rectification circuit during the generator mode.
