Due to the wind speed variation, continuous torsional torque fluctuation occurs from the drive shaft of the windmill. Twisting occurs between the wind turbine and generator due to the difference of the inertia of the windmill and the generator. As a result, the shaft may damage due to the metal fatigue of the shaft. Furthermore, measurement of the torsional torque is difficult in the actual machine. Therefore, a method for estimating the torsional torque is required. The proposed method estimates the torsional torque and suppress the torsional torque of the shaft by using the H∞ controller.","PeriodicalId":191469,"journal":{"name":"2013 1st International Future Energy Electronics Conference (IFEEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133528396","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 concept is composed of three capacitors, three diodes, one inputinductor and one coupled-inductor. By utilizing the leakage inductor energy to charge capacitor, and convert energy by the coupled-inductor, high step-up voltage gain and high efficiency can be achieved with an appropriate duty ratio. The voltage stresses on the main switch and output diode are reduced by a passive clamp circuit. Therefore, low resistance RDS(ON) for the main switch can be adopted to reduce conduction loss. In addition, the reverse-recovery problem of the diode is alleviated, and thus, the efficiency can be further improved. The operating principle and steady-state analysis of the voltage gain are also discussed in detail. Finally, a 24-V input voltage, 400-V output voltage, and 200-W output power prototype circuit of the proposed converter is implemented in the laboratory to verify the performance.","PeriodicalId":191469,"journal":{"name":"2013 1st International Future Energy Electronics Conference (IFEEC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133996493","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, the high-boosted voltage causes significant power losses. This paper proposes a power-loss reduction scheme by using an energy storage connected between Boost-converter and Bidirectional-Converter in Cascade (BBCC). First stage, the boost-converter makes a voltage boosting around 100V. Because of the low voltage-rating, we can use a schottky diode for the converter. In second stage, a bidirectional-converter makes a voltage boost up to 400Vdc. Using a schottky diode and a simple bidirectional-converter can reduce the power-loss significantly. To make the output power stable, the renewable energy system needs an energy storage. Compared to conventional energy-storage systems, the proposed-system is relatively cost-effective. In this paper, the operating principle and design guidelines of the proposed scheme are presented, along with the performance analysis. Also, a 350W BBCC hardware prototype has been implemented for experimental verifications of the proposed system architecture.","PeriodicalId":191469,"journal":{"name":"2013 1st International Future Energy Electronics Conference (IFEEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123631484","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, a typical power supply for LEDs exist the following drawbacks: (1) utilize bulky electrolytic capacitor as storage capacitor with short lifetime; (2) employ a low frequency diode bridge as the rectifier cell; (3) engage multiple stages cascade structure for multiple LED strings. To overcome the aforementioned shortages, a novel LED lighting driver is proposed in this paper. In this design, the non-cascade Twin-Bus configuration and bridgeless technology are utilized to increase the efficiency of LED power supply, while special DCM operation mode and valley fill circuit are introduced to eliminate electrolytic capacitors and reduce capacitor size.
