The filters are utilized to inject an expected distortion current and to shape up any distortion supply current for achieving a fully sinusoidal shape. In this paper, a new approach of single-phase shunt active power filterr (SSAPF) operation is presented. In contra with the conventional filters, the proposed filter acts as a new current pathway for the expected distorted current. According to the Kirchhoff's Current Law (KCL), the results of the summation of the SSAPF current and the load current is an almost fully sinusoidal current. The new SSAPF employing two sets of insulated gate base transistor (IGBT) and diode pair and the switching operation is controlled using unipolar pulse width modulation (UPWM) signal. The study focuses on the percentage of total harmonic distortion (THD) and the shape of the supply current when the proposed SSAPF is connected before and after the line inductor of the power system. From the simulation results, both connections are capable to improve the THD percentage below than 5%. Nevertheless, the filters are able to reshape the supply current to a fully sinusoidal wave shape. All presented simulation results were simulated by MATLAB/Simulink (MLS).","PeriodicalId":303729,"journal":{"name":"2012 International Conference on Power Engineering and Renewable Energy (ICPERE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122431832","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 SAPF provides a new current pathway for remaining distorted current when supply voltage is supplying a nonlinear load. Pulse-width modulation (PWM) switching signal is used to shape up the remaining distorted current to be complementary to the misshapen nonlinear load current. Therefore, total input current drawn from the supply always in fully sinusoidal shape. Safe commutation strategies are well developed to prevent overcurrent spike during the transition between half positive cycle and half negative cycle of the remaining distorted current. MATLAB/SIMULINK (MLS) is used to simulate and verify the operation of the proposed SAPF.

In this paper, we show that seebeck elements can be used for cooling system of LED lighting system. The cooling abilities of each system were studied to compare each LED cooling system. Each cooling systems consist of the only heat sink, seebeck element +heat sink, peltier element + heat sink. We used a 3W LED chip as light source and the LED chip were attached on a heat sink. The driving voltage of LED lighting is 10 V. In addition, either seebeck elements or peltier elements were attached between heat sink and LED substrate. The temperature of each cooling systems were measured by thermocouple and data was recorded by Data logger. As a result, cooling efficiency of LED with seebeck element is 9% higher than heat sink and 4% lower than peltier element. Therefore, peltier element is better than seebeck element on the performance of LED cooling, but peltier element was spent 0.4 W of power. Seebeck element is 9% less than peltier element on the performance efficiency of the cooling LED system. However 0.0035mW electric power was generated by seebeck element.","PeriodicalId":303729,"journal":{"name":"2012 International Conference on Power Engineering and Renewable Energy (ICPERE)","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114903696","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}

Configuration of imprecise plant combination will cause operating system becomes not optimal. Therefore the further study to evaluate the existing configuration and provide the results of an appropriate configuration for the operation of the hybrid system.
