The back-to-back AC-DC-AC multi-level power conversion stage for offshore wind turbines is usually driven by a Permanent Magnet Synchronous Generator (PMSG) for power ratings of the order of 6-10MW. The design approach, primarily relying on a comprehensive simulation model developed, aims to establish the power processing capability of the power conversion stage under the constraints of the thermal limits of the medium voltage power semiconductor devices, the power quality delivered to the grid (for power factor requirements of 0.9 to unity at the grid) and the overall efficiency. Based on the developed controls for the line-side and the generator-side converter, an instantaneous loss model of the semiconductor devices allows estimation of the instantaneous junction temperatures based on thermal models for the devices. Although the paper provides an overview of the different medium voltage power semiconductor devices, the analysis provided focusses primarily on the Integrated Gate Commutated Thyristor (IGCT). The maximum switching frequencies achievable at the power levels of 6-10MW is then determined based on the thermal constraints. Appropriate selection of the filter elements for the determined switching frequencies then enables quantification of the power quality and the overall system efficiency of the power conversion stage. The achievable switching frequencies at the different power levels of the line-side and the generator-side converters is finally established, along with the achievable power quality and efficiencies at the different operating points.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"1 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":"89833250","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}

However, when the duty cycle is constant in a line cycle, the input current contains rich 3rd harmonic which has a phase difference of π with fundamental component. The harmonic results in not only low PF but also larger peak and rms current values of the main power components, which leads to higher conduction and switching turn-off loss. A variable duty cycle control is proposed in this paper so as to enable that the input current contains only 3rd harmonic which is in phase with fundamental component while remaining the same PF at a certain input voltage, comparing with that of constant duty cycle control. A method of fitting the duty cycle is further proposed for simplifying the circuit implementation. The efficiency is improved as the critical inductance can be increased and the peak and rms current value is therefore decreased. The proposed method also achieves the output voltage ripple or the output storage capacitance reduction. The experimental results from a prototype of 120W are given to verify the effectiveness of the proposed method.","PeriodicalId":6508,"journal":{"name":"2014 16th European Conference on Power Electronics and Applications","volume":"25 4 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":"83347814","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}
