Course content

The course will give the cadet a basic understanding of power electronics, electric motor drives, conversion and control of electrical power using semiconductor technology. The course gives a basic introduction in the use of power electronics in electrical propulsion systems used in the Navy

STCW code tables: A-III/6 and A-III/7

STCW function: Electrical, electronic and control systems at operational and support levels. Maintenance and repairs at the operational and support levels.

The course covers the following academic content: Power semiconductors, single phase and three phase diode rectifiers. Phase-controlled rectifiers and inverters. Noise and noise conditions in electrical systems and systems. Harmonic components of periodic signals. Switched DC to DC converters. Switch-mode DC-AC inverters. Electric motor drives (Direct current motor and induction motor). Use of power electronics in marine electric propulsion systems. Uninterruptible power supply and other applications of power electronics in electrical systems. Practical laboratory work.

Learning outcome

Knowledge

After completing the course, the cadet is able to:

  • provide examples of various converters such as rectifiers and frequency converters and other power electronics that are used in marine electrical installations.
  • describe harmonic components as well as analyse and understand the impact of a marine electrical installation.
  • describe electric motor drives and marine electric propulsion systems used in the Navy.

Skills

After completing the course, the cadet is able to:

  • explain what characterises a power electronic system and a wide range of applications for power electronics
  • describe and analyse basic topologies of converters and have an understanding of grid effects from power electronic systems
  • describe electric motor drives, and make simple design sketches for power electronic systems
  • apply knowledge in power electronics and participate in laboratory work and master relevant methods and tools

General competences

After completing the course, the cadet is able to:

  • share his/her knowledge about power electronics and electric motor drives in relation to theories, issues and solutions.
  • know the structure and operation of marine electric propulsion systems
  • reflect on safety issues when working with power electronics and electric motor drives
Working and learning activities

Emphasis is placed on using examples from other subjects and from the service to illustrate topics in the course.
