Realizing a sustainable society will require a reduction in CO2 emissions, and many different sectors of the economy are being encouraged to be energy efficient, including the electric power business, industry, and consumer and transportation businesses. In the transportation sector in particular, environmentally conscious vehicles that use power electronics will be essential as replacements for conventional...
The reliability prediction of hybrid vehicles is of paramount importance for planning, design, control and operation management of vehicles, since it can provide an objective criterion for comparative evaluation of various structures and topologies and can be used as an effective tool to improve the design and control of vehicles. This paper presents a load-dependent simulation model based on MATALAB...
SiC MOSFETs are now commercial available and have demonstrated improved efficiency and higher operating temperatures over state of the art silicon components. Ongoing research activities have produced a massively-paralleled all-SiC module to examine the feasibility and reliability of high-current all-SiC modules. This paper documents a reliability study for a 1200-V, 880-A all-SiC dual MOSFET module...
Nowadays RAMS (Reliability, Availability, Maintainability and Safety) standards are widely used in the contract for the procurement of railway vehicles in the world except Japan. In spite of this Japanese railway has good punctuality and reliability in its operation. The author points out a difference between Europe and Japan in the railway business through the investigation activity of onboard inverter...
In this paper a test bench will be detailed in order to verify the reliability of new inverter prototypes for future EV and HEV electric motors. Cycling tests must be carried out in order to test the reliability of new components for inverters in the same conditions as in real vehicle. A test bench using 20-30 kW induction motor or brushless DC machines has been used. These machines are coupled with...
Vehicles powered by electric energy are considered to reduce CO2 emission but they must work properly under severe environment. In this paper, we report our efforts on the research like the crystal defect and the thermal stress analysis of power devices for hybrid vehicles. In addition, the inverter circuit simulation technique which simulates both the device loss and the temperature in state of the...
This paper presents principles and results of dynamic testing of an SRAM-based FPGA using time- resolved fault injection with a pulsed laser. The synchronization setup and experimental procedure are detailed. Fault injection results obtained with a DES crypto-core application implemented on a Xilinx Virtex II are discussed.
The soft-error vulnerability of flip-flops has become an important factor in IC reliability in sub-100-nm CMOS technologies. In the present work the soft-error rate (SER) of a 65-nm flip-flop has been investigated with the use of alpha-accelerated testing. Simulations have been applied to study the flip-flop SER sensitivity in detail. Furthermore, an easy-to-use approach is presented to make an accurate...
