Thyristor brush machine (TBM) is established as equivalent do machine without brushes and commutators. Since TBM is composed of polyphase drum type armature winding on the stator and polyphase thyristor bridge circuit, three phase ac voltage can be obtained at the same time with do voltage.<BR>In this paper, the characteristics of do or ac loading of TBM are investigated respectively and that of ac and do combined loading are discussed. Ac voltage of TBM can be stabilized by field excitation control, i.e., it is known as automatic voltage regulator, and do voltage, by gate control of thyristors. Power outputs on ac-dc parallel loading can be extended about 1.2 times as rated value as ac or do individual loading as for effective value of current of armature windings. It can be seen that the fundamental construction of TBM is much the suitable machine for marine use for small electrical noise, uniform torque generated and antiexplosion.
