Many SRM control schemes are based on current control, but the new technique exploits the linearity of flux control. The approach makes use of new methods of constraining flux demands according to available torque given by machine characteristics, and does not require any additional feedback signals; only current and rotor position are required. The implementation of the novel technique is described in detail along with simulation results to demonstrate its operation.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114964193","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}

This paper considers the non-inverting buck-boost converter used as a power optimizer, with emphasis on the control scheme applied to it. In the analysed configuration, the converter inductor current and PV voltage are controlled in a cascaded fashion, where the outer loop controlling the PV voltage provides the inductor current reference for the fast inner loop. With the selected control technique, the transfer functions describing the plant exhibit a first order like behaviour, hence facilitating the controller design, allowing to avoid using lead-lag networks or controllers whose tuning is non-trivial. The controlled converter performance in tracking the MPP voltage is analysed by means of simulations after a simple proportional integral (PI) controller is added in the voltage loop and another PI controller is adopted in the current loop.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114073891","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}

In order to ensure a fair comparison it is important to use the designs for each topology that are dimensionally comparable to each other. This is achieved by exploiting the ability of the Bi-Polar Pad (BPP), a hybrid flux pad topology, to be operated in different modes. This way the same design can be used not only to attain the results for a multi-coil/2-phase topology, but also the equivalent results achievable by similarly sized single-phase parallel (Double-D Pad or DDP) or perpendicular flux only pad (Rectangular Pad or RP) topologies. In order to evaluate and compare the effectiveness of the various cases, considered here, it is assumed that continuous transfer of power along the whole length of the track is desirable.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126514528","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 model is compared with previous T-joint design, Butt-lap, which is widely used at present by many transformer manufacturers. The magnetic flux density distribution and core loss of a transformer rated 1000kVA are analyzed for the two types of T-joint design. The 3D simulation are carried out by using the ANSYS-Maxwell software. The results show that the magnetic flux density of the hexagonal shape T-joint is well distributed compared to that in the Butt-lap T-joint design. The core loss for the proposed model (hexagon) T-joint indicates a reduction of more than 11 % compared to the Butt-lap T-joint design.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"235 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116391579","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 theoretical PTP voltages can be calculated with duty cycle ratio and DC input, and the real PTP voltages can be calculated with output voltages and currents. When no fault occurs, there should be no difference between the theoretical and the real PTP voltages. Once fault happens, great deviations between these two calculated voltages will be incurred and can be utilized to detect and localize the fault. This method is able to achieve fast diagnosing speed, while no extra hardware circuits and complex calculation are needed, thus it can be embedded in the existing control system with little effort. Furthermore, strong robustness against operation variation makes this method feasible in diversified applications. Simulations and experiments have been carried out to validate the correctness and effectiveness of this method.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116328178","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}

So it is necessary to have a research on the optimal control of different types of household loads so as to reduce power consumers' cost as well as to improve household energy efficiency. In this paper, an optimal control strategy of household energy efficiency management is presented, focusing on an electricity user who owns multiple types of household loads. In this control strategy, different types of household loads, the rooftop photovoltaic generation equipment, and as well as the household energy storage devices are all taken into account and modeled respectively. The coordinated optimal control of all these loads is discussed considering the time-of-use price. A numerical example demonstrates that the total power cost of a family can be reduced remarkably by carrying out the optimal control strategy proposed, and also, the utilization efficiency of the rooftop PV power generation equipment can be improved.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126089951","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 steady-state control-to-output curve is non-monotonic, and the Bode diagram varies significantly with the operating point. These characteristics lead to difficulties in closed-loop control. We reviewed two existing methods that are possible to address the closed-loop control problem: 1) operating at the split frequencies; 2) using a primary side current control loop. These two methods cannot fully address the problem or cause other problems such as low efficiency. We proposed an adaptive control method to handle the non-monotonic control-to-output curve. The method is verified by simulation but the parameters need to be further adaptively optimized for higher speed and accuracy.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126209126","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 aim of the study is to find the optimal size of the photovoltaic (PV) panel, wind generation system (WGS) and battery storage (BS) that can satisfy the varying load demand throughout the year. In the proposed PWB-HES sources and the battery are connected to a common DC bus. A voltage source inverter is used to connect the dc bus to the ac side. The optimal combination of sources and energy storage was obtained based on solar irradiance, wind speed and typical residential demand of the selected site. The optimal sizing algorithm was implemented using the HOMER software. The optimal system is then modeled and simulated with SIMULINK software in order to examine the complementary characteristics of the solar and the wind power system to satisfy the load demand. Simulation results showed that the PWB-HES with optimal size obtained through HOMER is able to meet the load demand amidst the changes in solar irradiance and wind speed.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129126578","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}
