The synchronous motor torque control, based on DTC structure, permits to obtain high dynamic performances. DTC is a concrete solution to robustness and dynamic problems found in other control structures. In DTC scheme, the requirement of the continuous rotor position sensor and co-ordinate transformation is eliminated since all the calculation is done in stator reference frame. However; the DTC scheme requires the position sensor to determine the initial position of rotor at starting. Elimination of the shaft mounted position encoder is a very desirable objective in many applications as this sensor is often one of the most fragile components in the entire drive system. This paper presents the implementation of DTC to Permanent magnet synchronous motor (PMSM) with a sensorless initial rotor position estimation scheme. The requirement of sensor for the initial rotor position estimation can be avoided by impressing a high frequency voltage on the stator winding. The simulation results verify the effectiveness of the process.","PeriodicalId":184844,"journal":{"name":"2012 International Conference on Advances in Power Conversion and Energy Technologies (APCET)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127381930","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 Drain voltage of power devices is varied in a known fashion against the input RF drive variations dynamically, to obtain better efficiency values over a range of output power. As a consequence, efficiency performances can be greatly improved as compared to classical back-off solutions. The employed 15-Watt C-band SSPA operates with 30% efficiency at an output power of 42 dBm. A coupler and detector from the PA provide a sample of RF input and a temperature detector provide the temperature data to the drain-bias controller, which is based on a buck dc-dc converter. The converter is designed with forward topology using resonant reset technique. Another low power push-pull converter is also used for providing housekeeping supply as well as low power supplies to the PA. When compared with a PA with constant drain bias (8V), the average efficiency of the PA with dynamic biasing is improved by 8.3%. Over an output power between 42-37.5 dBm, the drain bias varies from 8V to 5V, and the efficiency improves from 13.7 % to 22% at the lower power level. The efficiency figures include the losses in the dc-dc converter.","PeriodicalId":184844,"journal":{"name":"2012 International Conference on Advances in Power Conversion and Energy Technologies (APCET)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130578528","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}

Power failure is a serious problem which the mobile operators are facing frequently and Diesel Generators (DG) are the common mean to tackle this problem. But constant increase of fuel price is a big concern for optimum operation of telecom Base Transceiver Stations (BTS). Therefore mobile operators are finding this system very cost ineffective and difficult to rely upon. Environmental issue is another major concern as burning diesel fuel increases emission of Carbon-Di-Oxide (CO2) and other harmful Greenhouse Gas (GHG). Renewable energy i.e. solar energy based solutions has the capability to overcome these aforesaid complications in context of Bangladesh. This paper gives emphasis on grid connected BTS sites powered by Solar PV (SPV) arrays along with DG's. The simulation of feasibility study and optimization analysis of proposed model has been performed using HOMER software. From the results of the simulation it is evident that SPV-Battery based systems are really cost-effective although requires a huge initial investment and at the same time they are much more environment friendly than the existing system.","PeriodicalId":184844,"journal":{"name":"2012 International Conference on Advances in Power Conversion and Energy Technologies (APCET)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133953638","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 main objective of this paper is to minimize transient response specifications chosen as rise time, settling time and overshoot, for better speed response of DC motor drive. The speed control of DC motor is done using PI and PID controllers. Implementation of PID controller for DC motor speed control is done using ZN and MZN tuning method. For PSO algorithm technique, PI controller is used to improve the performance of DC motor speed control system. A comparison is made on the basis of objective function (rise time, settling time and overshoot) from output Step responses. The proposed approach had superior features, including easy implementation, stable convergence characteristic, and good computational efficiency. Fast tuning of optimum PI controller parameters yields high-quality solution. Compared with traditional ZN method and MZN method, the proposed method is found indeed more efficient and robust in improving the step response of DC motor drive system.","PeriodicalId":184844,"journal":{"name":"2012 International Conference on Advances in Power Conversion and Energy Technologies (APCET)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131737278","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}
