성원기 三陟大學校 2003 論文集 Vol.36 No.-
In this paper, a study of Norton's equivalent circuit using Pspice is described. This study is started with analyzing the circuits which is only comprised of resistances with independent sources and dependent sources. And then analyze the circuits which is comprised of resistances, inductors, and capacitors with alternating current sources. In this method, use the current source with 1 ampere to derive the equivalent impedance. Analyze theoretically and verify the results by use of simulation program, Pspice. Those results are coincident with each other.

This paper presents the analysis of induction motor characteristic. The mathematical model of induction motor was transformed into Pspice modelling using Pspice parts. The simulation result of proposed model was shown that Wrpm is 1879[rpm]at 1.0406[sec], when the parameters of model were chosen by Vdos=220[V], 60Hz, θ=-90˚, and ?=20[V]. It is confirmed that the simulation result is identified with the operation characteristic of real induction motor. In addition, the simulation was carried out using various values of ? parameters to analyze the characteristic of induction motor. It is also proved that the proposed model was shown identical result with real induction motor.

성원기 三陟大學校 1995 論文集 Vol.28 No.1
The control of two's stepping motors by one's exponential pattern control system is described. This method enable to drive two's motors in maximum rating speed. Two's stepping motors are accelerated in self-driving region on frequency-torque characteristics by exponential pattern and drived in slew region. Also, motors are decelerate in slew region on frequency-torque characteristics by exponential pattern and stopped in self-driving region. Minimum period of 0.0005 second expand speed-variation range. This system enables us to do the independent position and velocity control more economically than the trapezoid wave control. By experiment, the results is verified.

朴庚洙,成源基 三陟大學校 2000 論文集 Vol.33 No.1
This paper presented a design technique of the forward converter(30V, 5Vdc , 150W) using planar magnetic components is described. The application of planar magnetic components can solve the space problem which occurs when it is installed on PCB since planar transformer has low profile. In addition a lossless snubber circuit is added to reduce the device stress and to improve the system efficiency. The performance of designed system is verified by simulation and experiment by comparing the system using conventional magnetic components and the system using planar magnetic components.

본 논문은 와이파이 무선 인터페이스를 채택한 웹-기반 실시간 광생물 반응기 모니터링 시스템을 제안한다. 와이파이 무선 네트워크는 11Mbps의 고속 데이터 전송이 가능할 뿐만 아니라 기존 무선 랜 환경과 호환되기 때문에 쉽게 사용자의 요구에 따른 재구성형 광생물 반응기와 모니터링 시스템에 적용이 가능하다. 본 논문에서는 실제 상용 광생물 반응기에 와이파이 무선 데이터 전송 모듈을 탑재하여 무선 네트워크 환경을 구성하였고, 또한 여러 대의 광 생물 반응기의 배양 환경을 실시간으로 모니터링 할 수 있는 응용 S/W를 개발하여 동작을 검증하였다. 본 논문의 연 구 결과는 미세조류 장치뿐만 아니라 다양한 바이오 장치 산업의 핵심 기기들을 무선 네트워크로 연결하고 모니터링 환경을 구축하는데 적용할 수 있을 것으로 기대된다. This paper presents a web-based real-time monitoring system for a photobioreactor using an WiFi wireless network. An WiFi interface can support high speed data transfer, up to 11Mbps and it can be compatible with commercial wireless LAN environment. Thus, the proposed cell culture based on WiFi network can be easily applied to the reconfigurable system and real-time monitoring system. In this paper, we integrate the commercial WiFi module to the various bio-sensors and sensor control board to configure the wireless network. After we evaluate application S/W for monitoring the environment within incubator, we verify the proposed sensor networks for a cell culture system and its monitoring system. This result can be applicable for various bio-applications that require the network configuration and real-time monitoring system.
