Berzan, Iurie Ermurachi","doi":"10.1109/ISEEE.2017.8170654","DOIUrl":"https://doi.org/10.1109/ISEEE.2017.8170654","url":null,"abstract":"This paper analyzes a new architecture of the AC/DC type power supply for data centers. The source cumulates the following functions: three-phase current rectification, transformation of voltage parameters and DC voltage stabilization. The source ensures the reactive power compensation and does not distort the currents in the power three-phase network. The transfer of power from the alternating current network to the DC circuit is done at high frequency (over 100 kHz). The switching of semiconductor device is done in soft switching mode using Triangular Current Mode. The proposed algorithm for controlling semiconductor devices is performed at variable frequency in PWM mode. This leads to the reduction of loss in the switch regime of transistors. As a result, it is possible to increase the efficiency of the source to approximately 98%. The optimization of the switching mode of the semiconductor devices of the source with the power of about 0.5 kW does not require the use of radiators to ensure the thermal regime of the transistors. This leads, to the miniaturization of power supplies and the reduction of manufacturing costs. In the proposed source, the capacity of the direct current bus — the smoothing filter decreases a few times. At the same time it ensures the reduction pollution of the three-phase power supply circuit with superior harmonics. Verification of the proposed solution was done by mathematical simulations and by testing of a laboratory prototype of 2 kW. The AC supply voltage is 0.4 kV and the DC output voltage is 24 volts. The following mass indexes of the converter were obtained: the specific power 4 kW / kg.","PeriodicalId":276733,"journal":{"name":"2017 5th International Symposium on Electrical and Electronics Engineering (ISEEE)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131435838","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}

SISFREG will be connected between the catenary-line and the primary of the traction transformer, via a dedicated transformer. The main component of SISFREG is a shunt active power filter based on voltage source inverter structure, whose control guarantees the keeping of the prescribed voltage on the DC-side and the proper current at the inverter output by the indirect control of the supply current. The DC voltage controller is tuned in accordance with the Modulus Optimum criterion and the grid current controller is of hysterezis type. In order to verify the operation of the system and assess its performance, detailed computer simulation studies were conducted using the Matlab/Simulink package. Finally, a laboratory model was designed and build. In order to testing the system and showing its performances, an experimental setup was configured. The experimental results confirmed the good performance of the system during both traction/filtering and regeneration regimes.","PeriodicalId":276733,"journal":{"name":"2017 5th International Symposium on Electrical and Electronics Engineering (ISEEE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126597168","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 platform can operates autonomously by choosing an adequate signal processor or controlled by the powerful dSpace 1104 board, facilitating the rapid implementation of the design algorithms. At the same time, scalar and field oriented control of the three-phase asynchronous machine through the ControlDesk tool have been developed. Functional tests have been performed both on the control part and on the power section. In order to make safe tests of the modulation strategies the following have been taken into account: — operation of the voltage and current transducers both as independent device (to obtain the circuit information) and as an integral part of the control loop; — operation of the three-phase power IGBT module with the associated system circuits (galvanic isolation, drivers and control); — autonomous operation of the digital pulse width modulated signal (PWM) generating circuit.
