Abstract Ship electric propulsion since development began in the 19th century, has a long history。1832, first by the battery, DC motor driving power to promote vessel test success, on behalf of the power to drive the system to enter the field of the ship。 Power electronic devices and communication devices, high power AC motor variable frequency speed control technology, power transmission and control technology continues to progress and development, promote the continuous development and innovation of the ship electric propulsion system, and enlarges the application field, highlighting the broad application prospect。

Podded electric propulsion device by changing the traditional electric propulsion。 Placing the communication and synchronous motor and underwater pod, expanding the cabin capacity。 Using high performance variable speed technology, improve ship electric propulsion system dynamic performance and improve the ship maneuverability, reliability, and promote power and efficiency has been greatly developed。 Podded propulsion system to ship electric propulsion system has made great development, makes the electric propulsion in all kinds of yacht, ship, shipping and occupy the dominant position。

This paper mainly discusses the ship electric propulsion of basic structure and technical requirements of electric propulsion for comparative analysis, control and system construction from the perspective of the function of ship integrated power  system, discusses the generator and motor。 Focus on the ship propeller, propulsion motor performance, Frequency converter circuit topology, discusses the electric propulsion device structure design。

Through the design requirements of the small yacht ship electric propulsion, the calculation of the resistance of the ship, the choice of the generator, the modulation of the

frequency converter, the intensity and the design of the propeller, the design process of the electric propulsion system is completed。
