In order to achieve the requirements of the heat treatment, this paper proposes the method to control both the heater temperature and heater voltage for heat treatment by using two types of power regulators such as a high-frequency transformer and inverter system and a single-phase PWM inverter system. Both the hysteresis on-off control of the heater temperature and the open-loop heater voltage control for two power regulators are suggested in order to improve the performance of the heater temperature and voltage controls while ensuring safety. Experimental results are demonstrated for validating the performances of proposed control strategies of two power regulators.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126203893","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 salient feature of FI- PMa-SynRM is the ability to enhance the output torque and prevent PM from demagnetization although the PM amount utilized is minimum. To reach such feature, the maximum torque per ampere (MTPA)-based DTC control should be applied to FI-PMa-SynRM firstly, and the torque ripple is also investigated. T o reduce the torque ripple, the effect of stator flux errors is eliminated in the calculations of amplitude of voltage command, which is composited in the space vector modulation (SVM). The proposed DTC is comparatively investigated with the existing DTC in both computer simulation and experimental validation. The results validate that the modified DTC model achieves better torque ripple reduction and that on the other hand, dynamic response of modified DTC is lower than that of the conventional DTC.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126009751","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 results of numerical simulation show that (i) The peak output power has the maximum value, which increases first and then decreases with the increase of the thermoelectric couple length, and the conversion efficiency decreases with the increase of the thermoelectric couple length; (ii) The output power increases with the increase of cross-sectional side length, while the conversion efficiency decreases slowly; (iii) With the increase of chamfer, the output power decreases and the conversion efficiency increases.

This pole assignment of the full-order observer, in which robust flux estimation against velocity estimation error become possible, is obtained by solving a γ-positive real problem and a H∞ control problem.

Nowadays, DTC has been widely used in industrial applications thanks to its simple structure and high dynamic performance. However, hysteresis controllers cause high torque ripple and deteriorate control performance. In this paper, hysteresis controllers and traditional DTC switching table are replaced by a model predictive controller to achieve an online optimization for the required driving voltage space vector. Furthermore, a pre-selective process is designed to filter out the inappropriate voltage vectors and reduce computational burden caused by the eight basic voltage space vectors. Finally, an optimal duty ratio modulation method is proposed to determine appropriate zero voltage vector and the duty ratio of the selected voltage vector in each control period for torque ripple reduction. By implementing the proposed DTC, torque ripple is reduced and the approximated switching frequency can be minimized to retain the advantages of a traditional DTC; meanwhile, the torque response is still quick. Both simulation and experimental results exhibit the effectiveness of this proposed approach.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125701813","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}

As to this proposed scheme, the impedance of the traction network and the circulation and current-sharing characteristics between the traction substations are analyzed at first. In addition, the mathematical modes of the system are established with corresponding controller to obtain the compensated output voltage and phase angles between different traction substations to determine their current-sharing requirement.

To enhance the microgrid powering quality, a hybrid energy storage system including a battery bank and a flywheel, is equipped. Moreover, a plug-in energy support mechanism is developed to let the possible harvested sources be inputted to the microgrid through the same PV interface interleaved boost converter. As the PV output energy is insufficient to support demanded power, the converter cell in the interleaved converter is switched to accept the harvested sources.
