The newly revised edition of this material contains significant improvements and updates.

 

Integrated Electric Propulsion (IEP), characteristic of an Integrated Power System (IPS), enables the same set of prime movers to provide ship propulsion via electric motors and drives while simultaneously providing electrical power to non-propulsion (hotel) loads. While electric propulsion has been incorporated into ships for over a century, the introduction of affordable high power semiconductor switches in the late 1980's facilitated the wider employment of IEP in commercial and naval vessels.
