The proposed configuration relies on a Modular Multilevel Converter (MMC) topology as the grid interface of the charging infrastructure, where one wireless EV charger can be supplied from each individual module. This system topology could provide significant reduction in footprint and complexity of cable installations by allowing for transformer-less connection and direct integration with the medium voltage distribution grid. The requirements for power flow management when charging EVs that are unevenly distributed within the infrastructure are evaluated analytically. On this basis, a control strategy is presented for ensuring horizontal and vertical energy balancing among the MMC arms, and voltage balancing among the modules of each arm.

In most motor drive systems, the position and speed signals come from the optical encoder. Thus, to reduce the quantization error from encoder and achieve better speed measurement results are the focuses of scholars and engineers. Although many improved speed measurement methods have been proposed, there are still few literatures discussed about the frequency characteristic of the encoder quantization noise. Even in some algorithms like Kalman filter based speed measurement methods usually regard the quantization noise as white noise. In this paper, a noise frequency characteristic model of encoder-based speed measurement in motor drive is built up. According to this model, the variation rule of the noise frequency is found. Besides, a variable-period noise shaping method is proposed to reduce the impact of quantization noise. Both the notch filter and a finite impulse response (FIR) filter are used to cope with the quantization noise. The frequency model and noise shaping method are verified by experiment results.","PeriodicalId":423158,"journal":{"name":"2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131047096","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}

Energy harvesting produces electric power from surrounding energy and is the key to powering many IoT devices. A triboelectric nanogenerator (TENG) is a newly-introduced device that harvests electric energy from vibrational energy using the principle of electrostatic energy. Here, the characteristics of the TENG are determined to model and simulate under realistic operation using derating factors. Simulations using the ideal TENG's circuit model diverge significantly from the actual experimental results. Thus, derating factors are introduced to minimize error between simulation and experimental results. Derating factors of the internal voltage source and the capacitor of the TENG are defined and swept over a range of values to find the values that best fit to the experimental results. For the contact-mode TENG, a voltage derating of 0.0054 and capacitor derating value of 1 resulted in the lowest error in terms of power output. The comparison of the simulation and experiment shows that the they are matched with an error of 1.14 × 10−13A for current, 0.157 V for voltage, and 3.81 × 10−13W for power.","PeriodicalId":423158,"journal":{"name":"2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130837661","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}

Accordingly the DC-link capacitance can be drastically reduced and an electrolytic-capacitor-Iess PFC rectifier system featuring a higher power density and an increased lifetime is obtained. The proposed iSPPB concept consists of a simple full-bridge circuit with a buffer capacitor and is placed in series with the buck-boost inductor thus no additional inductive component is required for the iSPPB realization. The basic operating principle of the buck+boost PFC rectifier with iSPPB is investigated and the characteristic waveforms are presented. As shown in the analysis due to the employment of the iSPPB also the maximum buck+boost inductor current is reduced which compared to the conventional rectifier system without iSPPB allows to further downsize the inductive component. Consequently the major drawbacks of conventional single-phase PFC rectifiers are eliminated. Furthermore the control structure is presented and the proper operation is verified based on a closed-loop circuit simulation. Finally the proposed buck+boost PFC rectifier with iSPPB and a conventional two-switch implementation employing electrolytic capacitors are quantitatively compared by means of simple performance indices.","PeriodicalId":423158,"journal":{"name":"2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123287506","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}

Generally large electrolytic capacitors are used to eliminate the double line frequency ripple. It is well known that the low frequency ripple shortens the lifespan of the capacitor hence the system reliability may get worse. In order to eliminate the double line frequency ripple additional hardware combined with an energy storage device is required in most of the methods developed so far. In this paper, a novel power-decoupling control method is proposed to eliminate the double line frequency ripple at the front-end converter of the DC /AC power conversion system. The proposed control algorithm is composed of two loops, a ripple compensation loop and an average voltage control loop, and no extra hardware is required. Since the proposed method does not require any information from the phase-locked-loop (PLL) of the inverter it is independent of the inverter control. In order to prove the validity and feasibility of the proposed algorithm a 5kW Dual Active Bridge DC/DC converter and a single-phase inverter are implemented. The effectiveness of the proposed method is verified through the simulation and experimental results.","PeriodicalId":423158,"journal":{"name":"2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132734027","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}

Since RESs are normally coupled to electrical grids through grid-connected power converters, which do not possess any rotational inertia as conventional synchronous generators do, modern power systems will face frequency control challenges as the power system inertia continues to decrease. To address the lack of inertia concern, supercapacitor energy storage systems (SESSs) are implemented in this paper to generate virtual inertia by proportionally linking the grid frequency to the voltage references of supercapacitors. In this way, the improvements of inertia and frequency control can be achieved. More importantly, this paper discloses that the basic inertia control scheme introduces inertia emulation errors under large frequency disturbances. As a solution, this paper presents a nonlinear inertia control scheme, which ensures fair inertia emulation even under large frequency disturbances. Simulation and experimental results are finally presented to verify the effectiveness of the virtual inertia and the control schemes.","PeriodicalId":423158,"journal":{"name":"2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133715407","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}
