Abstract—Synchronous generators with ac and dc stator connections &nk[gb o\  
are widely used in systems where simultaneous ac and dc pPNU0]/  
power supplies are needed. For these systems the voltage harmonic ivKhzU+  
distortion of ac voltage, dc voltage ripple and dc voltage varying HH

range are of special interest. Because of the commutation of rectifier h`0'27\C  
and the saturation of magnetic circuit, the accurate calculation o0Y {k8
