Modularizing the battery cells/blocks with individual converters also provides the opportunity for redundancy and thus increased reliability. By adding additional series modules, modules with failed battery cells/blocks can be bypassed by their associated converter while maintaining system operation. In this paper, we assess the effect of converter distribution on system reliability. The results show that for low battery cell and converter failure rates, by proper redundancy choice, it is possible to design a highly reliable system. However, there is a compromise between the module failure rate (based on the cell and the converter failure rates); and redundancy level. For the modules with higher failure rates, the system reliability can be improved by applying annual scheduled replacement of failed modules. Using this approach, the six-sigma criterion can be achieved for a system of single/two strings of 30 V rated modules and the system of two parallel strings of 40 V rated modules. Further reliability-cost assessment is suggested to choose the optimum design for a specific application based on the influential factors such as: module voltage rating, module reliability, redundancy level, and scheduled-maintenance intervals.","PeriodicalId":188371,"journal":{"name":"The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128240667","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 four single phase permanent magnet (PM) transverse flux machine is proposed to achieve a certain power level at low speed (400 rpm) under the short circuit fault current constraints at higher speeds (15000 rpm). Due to a relatively small volume envelope of the proposed machine, a 3D parametric machine geometry was optimised within the given space by using several finite element (FE) optimisation approaches including genetic algorithm (GA) and design of experiment (DoE). The parametric machine geometry was further investigated to reduce the cogging torque and mutual flux linkages between the separate phases and also the manufacturing limitations have been accounted to build an alternator with soft magnetic composites (SMC). It is shown that the proposed machine achieves the performance specifications of the fault tolerant aerospace application but the proposed design comes with different averaged power levels at the phase outputs due to dissimilarity between mutual inductances, which are usually unavoidable in the axially positioned stators topologies with relatively very low synchronous phase reactances.","PeriodicalId":188371,"journal":{"name":"The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134176261","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}

The problem of torque ripple minimisation of OEW-PMSGs is addressed. Generally, the q-axis current injection method is employed to suppress the torque ripple. However, the third flux linkage parameters will be affected by high temperature when the machine is operating. In order to solve this problem, two sensorless adaptive control methods are presented in the following paper. The first method is based on adaptive sliding mode control and deadbeat-based predictive current control. The second method is based on model reference adaptive control with deadbeat predictive control. In these two control systems, a zero-sequence back-EMF observer (ZCBO) is used to estimate the zero-sequence back-EMF and zero-sequence current simultaneously and continuously. Meanwhile, the zero-sequence voltage which exists in the zero-sequence path and interferes the ZCBO's performance is considered. The performance of two control strategies is evaluated in MATLAB/SIMULINK environment.","PeriodicalId":188371,"journal":{"name":"The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131855312","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}

In order to tackle with this problem. This paper presents an inverter nonlinearity compensation method in permanent magnet synchronous motor (PMSM) drives. The overall process is achieved by voltage signal injection, the only requirements are stator resistance and the maximum current of a given motor. The corresponding voltage errors are saved in look up table (LUT) and being used together with field-oriented control (FOC). In addition, a comparative study when using phase current feedback, phase current reference and phase voltage reference for compensation voltages look-up in the already established LUT is conducted. A 750-W voltage-source inverter PMSM drive controlled by the FOC algorithm is used for experiment verification, the results show that the phase current reference is the most proper signal for compensation voltages look-up, especially around the current zero-crossing condition. The comparative study in this paper can be easily applied in the real industrial application with no hardware introduction and very little algorithm change.","PeriodicalId":188371,"journal":{"name":"The 10th International Conference on Power Electronics, Machines and Drives (PEMD 2020)","volume":"2020 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129526104","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}
