Electric propulsion, Power electronics

Developing the series on electric propulsion, this module covers the various types of power devices used in electrical propulsion systems. It explains the principles of rectification and inversion but also looks at maintenance requirements and how power electronic devices act as interfaces between electric propulsion control systems and power networks.

This course is the third in a series of four on the subject of electric propulsion. STCW 2010 requires OOW engineers to have knowledge of electrical motors and starting technologies, and need to be able to detect faults.

The seafarers in charge of electric propulsion systems need to know how to maintain them and how the systems work. This includes rectification and inversion knowledge and interfacing of electric propulsion control systems and power networks but also how to avoid failure.

Learning objectives:

• Know the various types of power electronic devices used in electrical propulsion systems
• Know how power electronic devices can be used as power switches
• Be familiar with the principles of rectification and inversion
• Know how power electronic devices are used to interface between electric propulsion control systems and power networks
