“…Therefore, the current problems can be summarized as follows: (1) The internal temperature and stress of power module can be obtained from the FEM, however, the long simulation time leads to low efficiency [22]; (2) Existing lifetime models have rarely been validated for accuracy under actual operation conditions [23], and internal stress effects are often neglected in the condition and lifetime estimation process. Limited by the above-mentioned problems and the number of urban rail vehicle stations [24], it is difficult to specify the conditions of the power module in the whole line.…”

In the actual operation of urban rail vehicles, it is essential to evaluate the condition of the traction converter IGBT modules. Considering the fixed line and the similarity of operation conditions between adjacent stations, this paper proposes an efficient and accurate simplified simulation method to evaluate IGBT conditions based on operating interval segmentation (OIS). Firstly, this paper proposes the framework for a condition evaluation method by segmenting operating intervals based on the similarity of average power loss between neighboring stations. The framework makes it possible to reduce the number of simulations to shorten the simulation time while ensuring the state trend estimation accuracy. Secondly, this paper proposes a basic interval segmentation model that uses the operating conditions as inputs to implement the segmentation of the line and is able to simplify the operation conditions of entire line. Finally, the simulation and analysis of the temperature and stress fields of IGBT modules based on segmented intervals completes the IGBT module condition evaluation and realizes the combination of lifetime calculation with actual operating conditions and internal stresses. The validity of the method is verified by comparing the interval segmentation simulation with actual test results. The results show that the method can effectively characterize the temperature and stress trends of traction converter IGBT modules in the whole line, which could support the fatigue mechanism and lifetime assessment reliability study of IGBT modules.

The conventional Static Var Generator (SVG) usually uses IGBT as the power device whose switching loss is high, and switching frequency is low, so the size of output filter and heat sink are large, which limits the improvement of its power density and efficiency. The switching frequency of SiC-MOSFET can be more than twice that of IGBT, and it can withstand higher junction temperature, so that the efficiency and power density of SVG devices can be further improved. This paper optimized the design of SVG from the perspectives of inverter topology, switching frequency, power device loss, device cost, filter, heat sink, etc., and proposed a 220V/50kVar SVG based on SiC-MOSFET discrete devices. It is two-level interleaved as the power topology, a single inductance filter as the filter, and its equivalent switching frequency could reach 100 kHz. The volume of the prototype built is 37L, 66% of the conventional IGBT-SVG product, and the power density is 1.35kVar/L, which is 1.62 times that of the conventional IGBT-SVG product. The peak efficiency of the prototype is as high as 99.03%, and the efficiency is up to 98.75% at full load.
