The paper regards dead-time effect and lagging effect as a periodic disturbance and proposes a lagging improved repetitive control to improve the accuracy of output voltage and reduce voltage distortion caused by dead-time effect. The control strategy does not need to detect the polarity of current and it saves current sensors which are used in traditional current closed loop.

This circuit is located to DC-link node in parallel and shows many performances such as energy buffer for decoupling ripple power and power factor correction (PFC) by controlling instantaneous system power. Therefore the diode rectifier system with ADLC does not need to equip additional PFC for satisfying grid regulations. Furthermore, since the ADLC can boost the DC-link voltage and supply the energy to the motor drive system while the DC-link voltage is lower than back electromotive force (EMF) voltage of motor, the drive system features constant torque and does not need excessive motor current for flux-weakening control in comparison with the conventional small capacitance motor drive system. This paper presents such a power control method and offers the design guideline of active DC-link circuit. The feasibility of the active DC-link circuit are verified by simulation results.","PeriodicalId":309780,"journal":{"name":"2014 International Power Electronics and Application Conference and Exposition","volume":"7 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133482732","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 proposed converter combines flyback cell and three-phase single-switched boost converter in order to achieve high step-up voltage gain at low input voltage and high efficiency at rated input voltage. The circuit is operating in discontinuous current mode (DCM), and thereby power factor correction (PFC) is also achieved. Since no electrolytic capacitor with large capacitance is employed, weak power can be collected at extremely low input voltage. At last, a prototype of 300W is built, operating with input phase voltage of 36.3Vac and output voltage of 365.5Vdc at rated, and its efficiency is 85% with the total harmonic distortion (THD) being less than 10%.","PeriodicalId":309780,"journal":{"name":"2014 International Power Electronics and Application Conference and Exposition","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116416511","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}

Development of the PWM converters has been spanning over a century, starting from the buck converter. The well known PWM converters include buck, boost, buck-boost, Ćuk, SEPIC, Zeta, Z-source, quasi-Z source, etc. Many attempts have been proposed to develop these converters based mostly on canonical cell concepts and by introducing extra LC filters to the cells. This paper presents an extended application of the Layer and Graft schemes, which is based on converter manipulation approach, to decode the PWM converters operated in either DCM or CCM. The PWM converters therefore can be derived systematically according to the codes or the input-to-output transfer gains. Decoding the PWM converters provides readers a physical connection between transfer gains and converter topologies, and a comprehensive understating of the evolution of the PWM converters from the original converter, the buck converter. Moreover, in this paper, the Ćuk, SEPIC, and Zeta converters all with the same transfer gain of D/(1-D) are proved to be identical to the buck-boost converter with an extra LC filter.","PeriodicalId":309780,"journal":{"name":"2014 International Power Electronics and Application Conference and Exposition","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123463489","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}
