Three experimental groups are conducted in order to test the feasibility of the proposed architecture.

The most reliable and significant approach, in order to contribute to minimize the harmonic pollution, is to treat each type of load autonomously. Therefore, this paper is investigating all types of power components for a filter circuit which is designed and used to reduce the harmonic amplitudes of the ac supply currents of a three phase six pulse controlled converter. The simulation results show that the filter circuit is active and reliable in the rectification and inversion modes, where dc machine is used as a load or prime mover in order to fulfill both rectification and inversion modes. The suggested method compared with the conventional type shows that a considerable improvements in effective power factor, minimizing harmonics and power distortion. Also different approaches have been presented for all types of power components.","PeriodicalId":432382,"journal":{"name":"2010 7th International Multi- Conference on Systems, Signals and Devices","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125853961","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 modification is done by adding vertical and horizontal stubs to the structure of the ordinary dipole antenna to reduce its length and broaden its bandwidth. IE3D full-wave electromagnetic simulator is used to simulate the modified dipole and compare it with the ordinary dipole antennas. The results showed that the modified dipole is shorter by (14%) and has wider bandwidth by (274.55%) which makes it able to cover the entire frequency band dedicated for UHF RFID systems (860 MHz ∼ 960 MHz). The modified dipole antenna is fabricated using PCB technology and its parameters are measured in an anechoic chamber.

The main objective is to overcome the drawback of voltage/current ripple which can be achieved by the reduction or elimination of the low harmonics frequency from the output voltage/current, to fulfill this requirement the SHE-PWM control algorithm is used, where the choice of the switching angles is based on the heuristic particle swarm optimization (PSO) method, therefore a new objective function is proposed presenting minimizing problem and the constraints of the switching angles sequences and the length of the chopping period. Finding the global minimum of this function leads to the elimination of the selected harmonics, whereas, keeping the average value of the output voltage equals to the desired value or the reference value.","PeriodicalId":432382,"journal":{"name":"2010 7th International Multi- Conference on Systems, Signals and Devices","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127664389","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 spite of their extensive use, these methods need either variable phase shifters or frequency sweeping. It is shown here that beam scanning is also feasible by varying magnitudes of the array element excitations thus alleviating the need for phase shifters or frequency variation. In this technique, the amplitude excitations of some side elements are reduced while those of the others are increased by proper power division or weighting in the feed network of the array. Theoretical analysis and computer simulations are presented to verify the proposed idea. A 3-element array is studied first, then the idea is extended to a 7-element array. Simulation results show appreciable scan angles with minor variation in the mainbeam level. Some degradation in the array pattern is noticed at large scan angles.","PeriodicalId":432382,"journal":{"name":"2010 7th International Multi- Conference on Systems, Signals and Devices","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114308645","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}

Many braking induction motor's strategies have been developed. Conventional braking modes are electromechanical such as braking with servo motor and counter current braking; then electrical one as direct current braking (DC). These two techniques have major drawbacks which limit their use. The first one is characterized by high braking current which reaches 7 pu and for the second one, brake torque is important only low speeds. In this paper a new electrical braking mode based on discrete variable frequency control (DFC) is suggested. Its is leading to significant reduction of braking current and improve the braking torque.
