Semiconductors degrade under the effect of thermal cycles. Thermal aging of materials occurs due to temperature difference between the elements of the power module as well as difference of their thermal expansion coefficients, which eventually leads to the destruction of the power module construction. The influence of thermal cycles is most expressed in traction drives, which are characterized by modes with low speeds and variation of commanded torque in time. This article considers a BMW i3 electric drive model and an open-end winding drive with Nearly Constant Losses Current Regulation for evaluating thermal cycles in a power module. The new European driving cycle was used as a test cycle for both drives. It is shown how the proposed algorithm makes it possible to reduce the thermocycling effects in semiconductor devices.","PeriodicalId":57487,"journal":{"name":"国际电力","volume":"18 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82066962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A mathematical model of the sphere-based robot system was developed based on the augmented model of the inverse pendulum. A linear state controller with an internal model of free movement of the object has been obtained. Verification of the developed control system is performed using simulation in MATLAB / Simulink.

The PWM technique with walking cell adapts to a different number of cells in the phase. However, in case of cell failure, the switching losses of each cell in the phase grow with respect to other healthy phases.

Two fundamentally different variants of solving this problem were identified - offline and on-line optimization. Off-line optimization requires a considerable amount of preliminary work, and the results obtained are applicable only to a specific motor type or similar. Known analytical dependencies for application in on-line optimization are either inaccurate or cumbersome and inconvenient for practical use. The algorithm proposed by the authors is based on the known idea of automatic on-line control over the first peak of phase current and moving it by control means to the angular position of the beginning of overlapping of stator and rotor poles. The algorithm recommended by the authors in the implementation requires minimal computing resources of the software part of the control system because it includes only the simplest calculations. Modeling in MATLAB-SIMULINK environment showed that under various perturbations, the transition of the SRM phase inclusion position control system to a new steady state is completed in no more than three cycles of motor switching.","PeriodicalId":57487,"journal":{"name":"国际电力","volume":"2012 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86405714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
