To implement in digital signal processors (DSP), the adjustability of switching sequences to reduce the harmonic contents of the output voltages and switching losses is very important. For this reason, the proposed control method is very suitable in comparison with the other modulation techniques that produce output voltages with variable frequency and magnitude. The proposed control scheme allows independent control of the magnitude and quadrature phase angle for two output phases. Thus, the presented two-phase inverter and its modulation scheme make the two-phase inverter commensurate with both balanced and unbalanced two-phase loads. Simulation results by using MATLAB/SIMULINK reconfirm the feasibility of the structure based on SVPWM method for the inverter.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126438201","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 converter is supposed to connect a battery bank to the DC bus. The main purpose of MPC method is to maintain the DC bus voltage in a predefined rated range, which means injecting active power to the DC bus to increase bus voltage and discharging the battery, and on the contrary absorbing active power from the DC bus to decrease bus voltage and charging the battery. The control strategy also disconnects the battery bank while DC bus voltage is in the predefined rated range. Simulations have been done in PSCAD/MATLAB software interfacing and results show the feasibility of the proposed controlling strategy to conduct active power on both directions.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126321805","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}

From the time of its start until it reaches synchronous speed, the motor produces a synchronous torque and an ideally flat speed/torque characteristic. The rotor of a hysteresis motor is a cylindrical tube of high hysteresis loss permanent magnet material without winding or slots. It is known that the hysteresis ring material magnetic characteristics plays an important role in flux distribution that can influence the output torque, terminal current and the efficiency of this motor. Regarding this issue, in this study effect of using new material for hysteresis ring on the performance characteristics of a radial flux hysteresis motor is investigated.

On the other hand, city gate stations (CGS), in which high pressure natural gas is expanded to much lower presser levels, has been proved to be a very suitable place for producing free electricity by employing turbo-expanders instead of conventional throttling valves. In this work, the feasibility of employing a CGS power output for improving the performance of a grid connected PV plant accompanied with a CAES system and enhancing its power output stability is studied. Comprehensive energy analysis and economic assessment on the proposed configuration is carried out and the results are discussed thoroughly. Finally, the performance of this hybrid configuration is compared with the PV plant and the CGS station while working individually. Internal rate of return (IRR) method as an authentic economic evaluation approach is used for comparing the considered systems economically.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125004653","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}

There are two switches, one coupled inductors and one capacitor in their structure, therefore the cost is reduced considerably. The proposed converters can be used as four quadrant DC/DC converter when fixed duty cycle (D) is applied to switches. On the other hand, they can be used as single phase inverter when the duty cycle is changed sinusoidal with time. In addition, the input voltage and the output load share the common ground. Therefore the leakage current is eliminated naturally in proposed converters when the photovoltaic source is applied as the input source.

According to norm-bounded linear differential inclusion (NLDI) notation, robust stability, and linear matrix inequalities (LMI) techniques, sufficient conditions are gathered to design the robust state feedback. Furthermore, based on internal model principle, the steady-state error is removed by adding a resonant controller.

Detecting the rotor initial position is a problematic step in these methods. In this paper a new method based on a probabilistic algorithm is proposed to find the position of the rotor at standstill condition. A set of diagnostic pulses are injected to stator windings for an unknown rotor position due to the inductance of each phase, different current responses are received. These responses are analyzed by an innovative algorithm, which is based on probability theory, to extract the rotor position in accuracy of 15 electrical degrees which is four times more accurate in comparison with earlier methods [9]. Due to the convergence feature of the used algorithm, the final result is completely faultless. This recognition method is very fast due the simplicity of calculations. A prototype driver is implemented with low-cost microcontroller and experimental results are demonstrated to validate the proposed method.","PeriodicalId":307121,"journal":{"name":"2016 7th Power Electronics and Drive Systems Technologies Conference (PEDSTC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117174742","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 proposed SVM technique for Class B-2 converter transfers the reference vector to the first sextant, and finds the number of triangles containing the tip of the reference vector and then using angular shifts transfers the triangles of the first sextant to their original sextants.
