With the extensive use of power electronics in modern HEVs comes the need for efficient methods of condition monitoring and fault diagnosis to ensure the reliability of the electrical power system. This paper addresses sensor faults in a DC/DC power converter system interfacing the main energy storage unit and the AC drive in a hybrid electric vehicle. A residual-based fault diagnosis system that...
This paper presents modeling, design and analysis of a bidirectional half-bridge DC/DC converter suitable for power electronic interface between the main energy storage system and the electric traction drive in hybrid electric vehicles. A hybrid energy storage system composed of a battery unit and an ultracapacitor pack is considered. A parallel dc-linked multi-input converter with a half-bridge bidirectional...
With the extensive use of power converters in modern hybrid vehicles, rises the need for efficient methods of condition monitoring and fault diagnosis to ensure the reliability of the automotive electrical power system. This paper is a technical review that studies power electronic devices and converters used in hybrid electric vehicles with a description of possible faults and a highlight on the...
This paper presents a study of different converter topologies used in the design of hybrid electric vehicle drivetrains with emphasis on the power electronic interface for a battery/ultracapacitor hybrid energy storage pack. Each of the topologies proposed in literature has its own advantages and disadvantages, thus choosing an appropriate topology depends greatly on the specified application, design...
This paper is a review of electrical simulation tools used for power system analysis with emphasize on applications based on renewable energy sources. The paper classifies simulation software into two classes: tools used for monitoring and controlling renewable systems and simulation tools used for modeling, designing, and simulating power systems.
A battery is a device that converts chemical energy directly to electrical one. In the context of renewable energy, the purpose of using batteries is to store the generated power from solar panels, wind turbines or from other renewable energy sources. In this paper, an overview of the batteries used in green energy systems is discussed. The health status of these batteries is treated. Finally, an...
