Compared to LLC converter, the proposed converter can achieve wide voltage regulation within relatively narrow switching frequency range, and also the proposed resonant tank can effectively transfer both fundamental and third harmonics elements, resulting in high conversion efficiency. By moving the LC notch filter of the LCLCL converter to the secondary side, the proposed converter avoids the circulating currents at primary side flowing through LC notch filter, which benefits to reducing conduction losses. The operation principles and characteristics are analyzed in detail using first harmonic approximation. A 400W prototype with input voltage range from 25V to 50V was built, and experimental results show overall efficiency of the proposed converter is 1.5% higher than LCLCL converter, which indicates the feasibility of the proposed converter in high step-up and wide voltage range applications.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126119464","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}

Continuous energy harvesting method was attempted using piezoelectric elements to supplement deficiency in micro scale solar generator system. Impact based piezoelectric generator has been studied as an enabling technology for high efficiency electricity generator, and continuous electricity generation using continuous impact has been tried to increase efficiency by increasing impact duty cycle. Horizontal wind flow was converted to rotating motion, and multiple blades in rotating wheel triggered high impact to piezoelectric element using spring action with increased frequency. This energy harvesting mechanism with cascaded connection of piezoelectric elements showed possibility of supplying sufficient power to sustain micro power sensor system.

The block commutation drive for IPMSMs would be an attractive method to achieve both high efficiency and high power density drives. In this paper, the equivalent SPMSM mathematical model of IPMSMs including the principle of the reluctance torque development is employed to directly apply the block-commutation control to IPMSMs. In addition, this paper proposes the advanced-angle adjustment with three times measurements of DC-bus current, which makes it possible to utilize two torques of IPMSM effectively, that means to realize the maximum torque per RMS value of the phase current.

In the studies of charge equalization, the switched capacitor type equalizer is popular due to its small volume and low cost.

Electrochemical impedance spectroscopy (EIS) is well-established for parameter identification; however EIS has traditionally been a laboratory procedure. With the recent prevalence of low-cost DSPs, it has become feasible to use EIS in online applications. This paper focuses on implementing EIS using a DC/DC converter topology commonly found in renewable energy applications. An AC ripple voltage is injected into the battery by modulating the PWM duty cycle, then the current and phase-shift response is analyzed to determine the frequency-dependent impedance. Voltage and current sensing devices have been developed so that the technique can be implemented on a TI F2833 DSP. EIS is performed at set intervals during entire charge cycles on test batteries in order to produce a data-driven model. Regression is performed using the Extreme Learning Machine (ELM) neural-network algorithm. The derived model is then verified by predicting the SoC of a battery used as a test sample.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"444 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133321641","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}
