Electric-Vehicle Power Converters Model-Based Design-for-Reliability

Abstract: Abstract-Fully electric vehicles are rapidly gaining user and market interest worldwide, due to their zero direct emissions, appealing driving experience and fashionable perception. Unfortunately, cost, range and reliability have not reached the desired targets yet. Since consumers are prone to spend money to have a more reliable system, Design-for-Reliability will be a useful tool for the Design of tomorrow's EVs, justifying part of the increased cost for these products. In this work, a vertical model-based a… Show more

“…As a result, many mission-profile-based reliability assessment procedures, which incorporate the DfR method and PoF understandings of power electronics, have been proposed and successfully applied for various applications (e.g., wind power converters [84], grid-connected PV inverters [85], variable frequency drives [86], or more electric aircraft [87]). For EV/HEV applications, the main focus has been placed on the reliability evaluation methodology of the power module used within the electrical drive train inverter [88]- [90]. Moreover, a thorough six-step mission-profile-based lifetime estimation procedure, which assesses the reliability of power electronics, both at the component level and the system level, has been proposed in [76].…”

“…This is achieved through the vehicle's mathematical models that take into account its mechanical parameters (e.g., mass, gear radio, wheel radius, and drag coefficient). The mechanical equations introduced in [90] (and their corresponding coefficients) have been employed, and the resulting speed and torque requirements of the PMSM are presented in Fig. 9.…”

“…The original idea has been applied to the reliability prediction of PV inverters in [16], and the same approach has been followed by the others [17]- [22]. This method has also been extended to the power converters used in wind turbines [23], motor drives [24], [25], power supplies [26]- [28], and electric aircraft [29] applications. However, the previous research fails to provide a guideline to select an appropriate number of simulations when applying the Monte Carlo method to the reliability assessment of power electronic systems.…”

“…Moreover, an increment of 10 • C in the operation mean temperature of a power semiconductor can double its failure-ratio [25]; consequently, special care of inverter thermal management must be taken. Such failures are a consecuence of the mismatches between the coefficients of thermal expansion of the materials that constitute power modules, which suffer from significant thermo-mechanical fatigue during thermal or power cycling [26].…”
