This paper presents energy management improvement for a Hybrid Electric Boat (HEB) applications using frequency approach. A variable speed Diesel-Permanent Magnet Generator (Diesel-PMG) is assisted by the lithium-battery to satisfy energetic demand of HEB. The lithium-battery module is connected to DC-bus through a buck-boost converter, and that of the variable speed Diesel Generator, it is connected...

This paper presents ultracapacitors (U) and lithium-battery connection with an energy management strategy based on the frequency distribution approach. The module of ultracapacitors is linked to DC-bus through the buck-boost converter, and that of the lithium-battery is connected to DC-bus without a converter. DC/AC converter (inverter) and electrical machine (EM) are used to emulate the Hybrid Electric...
The DC distribution in the multisource systems seems to be a reasonable solution because the supplied energy is in the DC form for several sources, such as the photovoltaic panels (PV), the batteries, and the Ultracapacitors. Additionally, the major parts of the used electronics devises in the buildings operate with the DC current, such as computers, air conditioning, and multimedia. Based on these...
This paper presents the Ultracapacitors (UC) and Fuel Cell coupling with an original energy management method for Hybrid Electric Vehicles (HEVs) applications. Ultracapacitors are coupled to the DC-link through Buck-Boost converters. The Fuel Cell is connected to the DC-link using boost converter. An asynchronous machine is used like traction motor; it is coupled to DC-link using an inverter. The...
