However, such control algorithms such as Perturb-and Observe (P&O) method usually require DSP or customized control ICs. This leads to high power consumption and high cost. This paper proposes a novel strategy to realize max. power delivery through coil connection switch approach where the input impedances and voltage/current levels are adjusted according to different output voltages. A single stage AC-DC dual boost converter is employed with fixed duty cycle to charge a super-capacitor load to verify the concept. Three sets of harvester coils are used and are connected in either parallel or series. The switch of coil connections is realized through isolated analog switches. It is demonstrated that the harvester with dual boost converter under proposed strategy achieves an maximum output power of 3.628 mW in 0.2 g acceleration, which is 41.7% higher than same converter without coil connection switching. With proposed method, the output power reaches to 98.7% of the output power with traditional P&O MPPT strategy. It also achieves higher efficiency and more compact system size than traditional P&O MPPT.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125077200","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}

An adaptive pre-synchronization method is proposed for uVOC to enable smooth start-up and seamless connection to an existing grid/network with non-nominal frequency and/or voltage magnitude at the point of coupling (PoC). Furthermore, we evaluate the efficacy of different discretization methods for discrete-time (DT) implementation of the nonlinear dynamics of uVOC and demonstrate that zero-order-hold (ZOH) discretization fails at sampling frequencies up to tens of kHz. DT implementation of uVOC using second-order Runge-Kutta method is presented, which offers a reasonsable compromise between computational overhead and discretization accuracy. In addition, an inductor (L) or an inductor-capacitor-inductor (LCL) type input filter used in typical voltage source converter (VSC) applications leads to voltage deviation at the converter output terminal depending on the power flow. A terminal voltage compensator (TVC) for such voltage deviation is proposed. The efficacy of the proposed methods are demonstrated through laboratory hardware experiments.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123686130","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}

To achieve this, the scaled-down machine has been customized by modifying the stator and rotor windings such that various inter-turn winding fault conditions may be achieved at different severities. Moreover, the micromachine has also been modified to make it possible to implement a static eccentricity fault. The dimensional analysis & scaling methodology that was used to scale down the large scale DFIG into the micromachine has been briefly discussed in this paper. To evaluate the performance of the developed test rig, experiments have been carried out by separately implementing the stator and rotor inter-turn short circuit faults (ITSCFs) as well as the static eccentricity (SE) fault on the micromachine and capturing the real-time stator current signals for further analysis in MATLAB, in an attempt to diagnose the presence of these faults using the conventional motor current signature analysis (MCSA). The results obtained from the stator current spectral analysis have demonstrated that the presence of a stator ITSCF, rotor ITSCF and SE fault in the micromachine gave rise to additional frequency harmonic components in the stator current spectrum. Moreover, it was observed that the magnitudes of the fault-related frequency components increased as the interturn winding fault severity was increased. Therefore, the developed test rig can be successfully used for further fault studies and ultimately develop advanced and novel fault diagnosis techniques.","PeriodicalId":349891,"journal":{"name":"2021 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125246778","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}
