These distortions are more critical when the converter switching frequency increases and in applications requiring high di/dt. This is especially true for power converters used to supply pulsed electro-magnets in particle accelerators where output waveforms with high slew rates are needed. Several solutions exist to compensate the distortions caused by dead-time; however, in fast and precise applications, the compensation method should be analysed in conjunction with design choices, such as the selection of switching frequency, output filter's inductances and topology. At CERN, hybrid capacitor discharge/switch mode power converters have been developed to supply electro-magnets used for PS beam injection. For standardisation and cost reduction. Because of this design option, dead-time represents 16 % of the switching period thus widely affecting the converter performances. This paper illustrates the effects of dead-time on various design aspects of these hybrid power converters able to produce precise 1ms long current pulses with maximal output current up to 2,5 kA. The converter control loops that have been designed using Energetic Macroscopic Representation approach can partly compensate for the dead-times effects. However, a dead-time compensation technique based on the inductor current sign measurement is nevertheless required to improve the converter performances. It is experimentally demonstrated that this classical compensation method is effective, even in interleaved switching module.","PeriodicalId":241752,"journal":{"name":"2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115027775","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}

Due to the massive integration of RES into the electrical power system among DC microgrids, critical challenges have been aroused in controller design and its operation. In large-scale DC microgrids, complexities and control requirements are complicated than small scale grid. Existing primary and secondary cooperative control structures rely on PI controllers that make them vulnerable at higher nodes. In this paper, by considering the DC microgrid control requirements, structural improvements have been suggested to improve controller stability and performance. A droop-less control scheme has been proposed in this paper by augmenting a finite gain controller in voltage loop with PI controller in the current control loop of DC/DC converter. A different strategy has been employed at distributed secondary control for the estimation of average voltage and current difference. The proposed droop-less controller offers several benefits such as simplicity in the control structure, higher stability, higher scalability, and overall better system reliability. The simulation results in MATLAB/Simulink setup verify the controller efficiency and feasibility. Moreover, voltage control bandwidth comparison is presented while considering communication delays and in the presence of a higher system nodes.","PeriodicalId":241752,"journal":{"name":"2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114115520","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 this paper, we describe the characteristics of a novel motor capable of pole and phase changes; it is a high-performance motor because it has multiple windings combined with multi-inverters. The pole changes will allow the motor to operate with a large torque at a low speed by using a small number of poles; the motor can operate at high efficiency at high speeds by using a large number of poles. The motor had three groups of three-phase windings consisting of 18 coils. One group of the three-phase windings was consisted of 6 coils. Three three-phase inverters that connected the three groups of three-phase windings directly controlled the current phase of each winding, which helped change the number of poles and phases. The results of our analyses confirmed that the motor produced a large torque at a low speed of 3000 rpm for the eight-pole mode, and operated with a high efficiency of approximately 96% at a high speed of 6000 rpm for the four-pole mode.","PeriodicalId":241752,"journal":{"name":"2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)","volume":"446 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116755108","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}

For this purpose, a combined power cycling test (PCT) and high humidity, high temperature, reverse bias (H3TRB) reliability test was performed. In order to quantify a possible impact based on the amount of previous stress, devices of different health conditions were used. Some devices were subject to power cycling for 50% of their estimated cycles to failure before being tested in an H3TRB test. Other devices were preconditioned in power cycling until the end of life criterion was reached before they were subject to the H3TRB test. The results of this work indicate that previous thermo-mechanical stress does have an impact on the H3TRB performance of at least some of the tested devices. Furthermore, the test results do not clearly indicate a significant difference between the devices, which were preconditioned with 50% of their cycles to failure and the devices, which were subject to power cycling until end of life.","PeriodicalId":241752,"journal":{"name":"2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117124606","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}
