High Temperature Nanoelectronics for Electrical and Hybrid Vehicles
Keywords: High Temperature Nanoelectronics, Semiconductor Technologies, Electrical and Hybrid Vehicles
The next generation vehicles will be cleaner and more energy efficient. The advancements will be mainly due to the developments in power electronics and distributed embedded-based control systems. Today, there is a significant trend in the automotive industry to use more electrical systems and to combine the internal combustion power train with electrical power systems. This means that the demand for advanced high temperature reliable electronics systems will increase. In order to satisfy this new demand, new nanoelectronics semiconductor technologies are developed and used to integrate power electronics modules within advanced vehicular power systems. In this context this paper aims at reviewing the present semiconductor technologies as well as future research and development work of advanced nanoelectronics semiconductor technologies, devices and circuits for electrical power systems including those of electric vehicles (EVs) and hybrid electric vehicles (HEVs). New concepts will be reviewed for power train, power conversion, power management and battery management. These systems are considered to be fail-safe, redundant and fault tolerant and new methods and technologies for improved reliability and increased lifetime will be described. The paper will introduce the power system architectures for EVs and HEVs and will present the specific applications of DC-DC and DC-AC power electronic converters in advanced automotive power systems and the high temperature electronics design issues, based on the voltage/current range of needed modules, with focus on energy efficient semiconductor technologies.
