BIPV(Building Integrated PV) system that is united on constituent outer covering of building can expect dual effects that reduce expenses for establishment of PV system by adding new function as outer covering material of building except producing the electricity. Also, it is a profitable technology in the economical field because it does not need the building site for a special purpose for the establishment as existing stand along PV system. In this paper, it was simulated through the theoretical consideration about output characteristic analysis of PCS and web-based monitoring of 10kW BIPV, finally was examined the validity through the experiment. BIPV system that is proposed in this paper, was established in BIC(Biotechnology Industrialization Center) of Dongshin University, composed with PCS and Web-monitoring system.

태양광 발전 시스템의 운용에 있어서 부하의 변동, 일사량, 주변온도등에 의한 최대전력점의 추종은 매우 어려운 기술을 요구한다.<br/> 본 연구에서는 이러한 최대전력점의 추종에 있어 빠른 수렴 특성을 얻기 위한 알고리즘으로써 신경 제어기법을 이용하여서 기존의 제어 방식에 의한 동특성과 비교하여 적절한 제어기법 및 시스템동작의 우수한 특성을 얻게 되었다. 즉 최대전력점의 추종 및 안정한 전원의 공급을 갖게되었다. A maximum power point tracking (MPPT) converter, to enhance the converter efficiency is evaluated within the laboratory. The converter is controlled to track the maximum power point of the input photovoltaic (PV) source by varying the input and output parameter- conditions of irradiation, temperature, etc. The purpose of this paper is to develop a new maximum power point tracking (MPPT) using neural controller. Neural controller are applied to control of MPPT by boosting converter duty ratios compensation effect with 8 bit single chip 8051 microcontroller.

In this paper a drive strategy of DC servo motor using the fuzzy algorithm of auto-tuning PID control was proposed. According to the purpose of high speed, the preclsion and the extension of applicated region, motor act an impotant role with variety of sort. So DC servo motor of excellent control capability is used. During the past severl years.fuzzy control has emerged as one of the most active and fruitful area for research in the applications of fuzzy set theory, especially in the realm of industrial process,which do not lend themselves to control by conventional methods because of a lack of quantitative date regarding the input-output relations. Fuzzy control is based on fuzzy logical system that is much closer in spirit to human thinking and natural language than traditional logical systems. For high performance and high accuracy of the drving system,using the fuzzy algorithm,the driving system which has the auto-tuning fuction is designed and proposed

The Modeling, analysis and design of a high frequency LCC-type parallel resonant converter (LCC-PRC) and LLC-type parallel resonant converter (LLC-PRC) operating in the continuous conduction are presented. It will be shown that at switching frequency lower than the resonant frequency, the gain of this converter is lower than the gain of conventional, parallel resonant converter with LCC-type and LLC-type commutation. A set of characterisric frequency is plotted which design parameters can be obtained.

By using the state plane approach the steady state analysis and design of a half bridge parallel-series(LLC-type) resonant converter (HBPSRC) operating in the continous conduction made is presented. The state-plane diagram representation of the converter response gives good insight into the converter operation. Based on this analysis, a set of steady state characteristic waves for HBPSRC is presented. A simple design procedure is given and design example for a 100watts, 30KHz HBPSRC is presented for illustrative purposes.
