The proposed topology consists of two series resonant tanks. Each series resonant tank is built up by connecting a tank capacitor in series to a high-voltage transformer with the leakage inductance of the high-voltage transformer is absorbed as resonant inductor. Therefore, two high-voltage transformers are used in this topology with their primary windings are connected in series. The secondary output of both transformers are boosted by half-wave voltage multiplier and mixed before supply to load. The series resonant tanks are energized alternately by controlling two IGBT switches with pulse frequency modulation (PFM). This topology is operating in discontinuous conduction mode (DCM) with all IGBT switches are operating in zero current switching (ZCS) condition and hence no switching loss occurs. Moreover, this topology has low conduction loss as it requires only half number of IGBT switches compared to conventional full-bridge inverter based SRC. The effectiveness of the proposed topology is verified by simulation using OrCAD PSpice and the simulation results will be presented.","PeriodicalId":325846,"journal":{"name":"2012 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129297945","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}

Solar power generation is one such alternative, and Concentrated Photovoltaic Technology (CPV) is one of the two main technologies used for producing electricity from Concentrated Solar Power (CSP). Meteorological parameters such as solar irradiance and cell temperature when the sunlight is concentrated on the CPV module influence the efficiency of the CPV power generation systems. Additionally, the output power of a CPV plant must be measured and monitored to improve the condition of plant, again in terms of efficiency and reliability. Firstly, in this paper, the significance of the meteorological parameters and the CPV system parameters are discussed. This is followed by a description of proposed multichannel data acquisition and logger for CPV technology. Experimental results have proven a good level of accuracy of the proposed system in terms of the acquired meteorological parameters and CPV system parameters.","PeriodicalId":325846,"journal":{"name":"2012 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126864576","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 frequency divider architecture is based on the low power high speed triple-modulus prescaler design. The triple-modulus prescaler supports three division modes (N/N±1) via the phase switching between the output signals of the master/slave emitter-coupled logic divide-by-two stage. The novel N-1 division mode is achieved by modifying the low frequency phase selection control logic. The wide division range is achieved by cascading the prescalers. In addition, the 50% duty cycle baseband clock is derived from the divider chain. The frequency of the baseband clock is equal to 499.2 MHz regardless of the chosen center frequency (in combination with the corresponding division ratio) for the multi-channel system designed for IEEE 802.15.4a standard. The measured maximum input frequencies of the divider for each of the required division ratio prove that the presented divider satisfies the specification. The measurement results demonstrate that the presented frequency divider can be used in the frequency synthesizer for generation of the center frequencies for multi-channel transceiver designed in accordance to IEEE 802.15.4a standard. The measured power dissipation of the programmable frequency divider is equal to 31.2 mW from 2.6 V supply voltage.","PeriodicalId":325846,"journal":{"name":"2012 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127969096","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}
