“…Power electronics are key elements in a wide range of technologies such as smart electric grid, [1] renewable energy, [2] and electric vehicles [3]. Power MOSFETs based on wide band-gap semiconductors such as SiC [4] are important types of power electronics that are gaining momentum in both research and commercial arenas.…”

MOSFETs based on wide band-gap semiconductors are suitable for operations at high temperature, at which additional atomic-scale processes that are benign at lower temperatures can get activated which results in device degradation. Recently significant enhancement of electron trapping was observed under positive bias in SiC MOSFETs at temperatures higher than 150°C. Here we report first-principle calculations showing that the enhanced electron trapping is associated with thermally activated capturing of a second electron by an oxygen vacancy in SiO 2 , by which the vacancy transforms into a new structure that comprises one Si dangling bond and a bond between a five-fold and a four-fold Si atoms. The results suggest a key role of oxygen vacancies and their structural reconfigurations in the reliability of high-temperature MOS devices.

“…To respect the race rules, no battery other than an auxiliary is allowed in the powertrain system. Thus, 2 kinds of FC powertrain structure can be considered [9]: the direct powertrain system, see Figure 6 (a), and the indirect power train system, see Figure 6 (b). Since the race does not require the vehicle to stop and start nor excessive braking, and is run on an almost flat road, the ultracapacitors can be removed from the designed powertrain system.…”

This paper reports the analysis of an automatic intelligent controller for driving a prototype fuel cell electric vehicle over different obstacles while maintaining all systems at maximum efficiency during completion of a race within a specified time. The objective is to reduce driving errors, such as excessive driving, or over revving the throttle while controlling the energy usage at the minimum point and improving driving skills for the Shell Eco-marathon Asia 2014 race. The vehicle is equipped with a proton exchange membrane (PEM) fuel cell system, a brush DC motor and a DC/DC converter. This prototype vehicle is a single-seater type of car and has a streamlined body shape that is designed for energy-efficiency racing where the objective is to achieve the furthest distance with the least amount of fuel in a specified time. In the design process, the car's fuel-cell efficiency, energy demand, track behavior, motor efficiency analysis, and driving control strategy need to be monitored and used to verify the designed automated intelligent controller. Experiments on the automated intelligent controller were undertaken to analyze the performance of the powertrain system for a certain given time. This powertrain system for automated intelligent controller analysis is part of the energy efficiency study of the electric vehicle. It forms the knowledge base for the next detailed energy efficiency analysis.

“…Since the forecasting of wind speed and the time when wind blows is too difficult due to the fact that wind speed is an uncertain parameter, wind power generation would be Storage System (ESS) [93][94][95][96][97][98][99][100][101]. The most common ESS is battery.…”

Nowadays, the world is encountering severe challenges in the energy generation sector. Environmental issues like climate change, global warming and Green House Gases (GHGs) and also social issues like dramatic increase in global population and increasing energy demand are the main causes of global concerns about energy resource management. In this regard, Renewable Energy Sources (RESs) are the suitable substitution to replace the conventional generating units that emit GHGs due to the use of fossil fuels. Among all RESs, wind energy seems to be promising for generating emission-free electrical energy. However, it is naturally unpredictable due to its intermittency which leads to s ome technical problems such as generation imbalance as well as optimal reserve allocation. This paper investigates the solutions to compensate wind intermittency through introducing various technolo gies such as Pumped-Hydro Storage (PH S) units, Plug-in Hybrid Electric Vehicles (PHEVs), solar energy and other electric storages like batteries. Abstract-Nowadays, the world is encountering severe challenges in the energy generation sector. Environmental issues like climate change, global warming and Green House Gases
