The present invention relates to a bipolar DC distribution and dual voltage power generation system for a ship. The bipolar DC distribution and dual voltage power generation system for a ship according to an embodiment of the present invention comprises: a generator that has a main voltage of 2*Vdc as a main power generation voltage, and has Vdc voltage as a power generation voltage through additional multiple windings; and a switchboard providing each three-phase output voltage through a plurality of output windings of the generator, wherein the switchboard is characterized in that the output voltages of each of the three phases provided through the plurality of output windings have at least two different voltages. An objective of the present invention is to supplement the disadvantages of an existing power converter and to increase the power conversion efficiency. 본 발명은 선박용 양극성 DC 배전 및 이중 전압 발전 시스템에 관한 것으로, 본 발명의 실시예에 따르는 선박용 양극성 DC 배전 및 이중 전압 발전 시스템은 메인 전압인 2*Vdc 전압을 주 발전전압으로 가지며, 추가 다중권선을 통해 Vdc전압을 발전전압으로 갖는 발전기 및 상기 발전기의 복수의 출력권선을 통해 각 3상의 출력전압을 제공하는 스위치보드를 포함하며, 상기 스위치보드는, 상기 복수의 출력권선을 통해 제공된 각 3상의 출력전압이 서로 다른 적어도 2개의 전압을 갖도록 하는 것을 특징으로 한다.
