In this system, the torque and the frequency have to be regulated simultaneously, in order to make the prime mover operating at the maximum power point and to guarantee at the same time a flux level near the rated value. Since this system is based on a unique reduced-power controlled converter and a diode rectifier, a noticeable reduction of the costs of the power electronics can be achieved. However, the diode bridge causes stator current and voltage harmonics which produce a noticeable torque ripple. A regulation scheme able to reduce the torque ripple is proposed in this paper: resonant current controllers are implemented to track the sixth harmonic components in the reference rotor current commands, in such a way to kill the corresponding harmonic in the electromagnetic torque.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"38 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89576936","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 circuit can achieve ZVS for the full range via triangular current mode (TCM) and unlike conventional buck PFC, the circuit can operate for the entire cycle. The bridgeless topology has fewer numbers of components in the conduction path than any other bridgeless boost PFC circuits. The ideal full control is discussed and a simplified control is also proposed which has almost the same efficiency with a simulated peak value of ~97.5%. This circuit also exhibits an interesting property of higher efficiencies at low load conditions which could be of interest for SMPS for laptops and computers.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"65 5 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89279769","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}

Finally, according to the harmonic eliminating principle, compares WPWM with SPWM technique by some specific examples. The calculation and simulation results show that WPWM can get simpler realization by digital algorithm, higher fundamental component magnitudes and lower THD factors, but the range of fundamental component magnitude is smaller and the ability of eliminating lower harmonics is worse, which provide theoretical basis for the application of the WPWM efficiently in practice.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"123 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86667957","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}

By connecting balancing converters around each pair of adjacent PV panels, all panels can maintain the operation close to their MPP regardless of any mismatched operating condition. In this paper a balancing converter concept with ZVS is introduced and the operation of a string of PV panels equipped with balancing converters is analytically described. Based on this analytic framework, different examples of shading scenarios of a PV string are examined regarding the average inductor current values that occur within the balancing modules, in order to derive the required specifications of a balancing converter. Moreover, a two-level overcurrent protection concept is introduced which enables to keep all balancing converters within the safe operating area at all times, even at shading conditions with high mismatch. Furthermore, the design optimization of a highly efficient PV voltage balancing converter with a wide input voltage range is explained in detail and finally the concept is verified with measurement results of a demonstrator system.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"30 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2014-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81242998","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}
