Abstract - An electronic starter using MOSFET has been designed to take advantage of ideal preheating and starting features which can extend the lifetime of fluorescent lamps. The preheating circuit of the developed electronic starter is consisted of four parts - afull-wave rectifier circuit, an FET switching circuit a timer circuit for the gate switching, and a circuit for end-of-life protection. The circuit is analyzed by using PSpice simulation, and is improved to give an appropriate starting-time through control of R-C time constant of the timer circuit. And the circuit is also provided with an end-of-life protection feature, which utilizes the negative resistance characteristics of a thermistor that is thermally linked to FET through a heatsink. This also protects the FET from any overheating problems. From the results of simulation it is possible to obtain an appropriate value on the starting time for proper ignition and also it is verified that the limit for resistance of the thermistor is dependant on the value of resistance is the timer circuit

This paper presents an electrical feature analysis of hysteresis curves in memristor differential and intergral control circuit. After making macro model of the memristor device, electric characteristics of the model such as time analysis, frequency dependent DC I-V curves were performed by PSPICE simulation. Also, we made a circuit of memristor-capacitor based on nano-wired memristor device and analyzed the simulated PSPICE results. Finally, we proposed a memristor based differential or integral control circuit, analyzed hysteresis curve characteristic in the control circuit.

The advancement of power semiconductor devices has given great attribution to the performance and reliability or power conversion systems. But contemporary power devices have room for improvement. So much interest and endeavor are being applied to develop an improved power devices. The MOS-Controlled Thyristor(MCT)is a recently developed power device which combines four layers thyristor structure and MOS-gate. Owing to advantages compared to other devices in many respects, the MCT attracts much notice recently. Nowadays, in designing and manufacturing power conversion systems, the importance of circuit simulation for reducing cost and time is incensed. And to excute the simulation that resemble the real system as much as possible, to develop a model of power device that provides properly static and dynamic characteristics is important. So, this paper presents a PSPICE model of the MCT considering dynamic characteristics.

We have proposed the methods how to control the slope of CMOS inverter's characteristic and how to shift it in y axis. We control the MOS transistor threshold voltage for these methods. By observing that two transistors are in saturation region at the center of the CMOS inverter's characteristic, we have presented how to make the characteristic for one pole neuron. The circuit level simulation is used for verifying the proposed method. PSpice(OrCAD Co.) is used for circuit level simulation.

The purpose of this study is to verify the effect of PSpice instruction on academic achievement in 'Combination logic circuit' unit of 'Digital Logic Circuit' in industrial high school. Three kinds of null hypotheses were formulated. Two classes of the third grade of C technical high school in Gyeong-buk were divided into experimental group and control group in order to verify null hypotheses. In the experimental design, 'Non-equivalent control group pretest-posttest' model was utilized. This experiment was conducted for six classes, the experimental group was applied to PSpice instruction method before the circuit traning while the control group was applied to traditional lecture oriented method before the circuit traning. Window SPSS 10.0 korean language version program was used for the data analysis and independent sample t-test was used to identify the average of each group. Significance level was set to .05 level. The results obtained in this study were as follows; First, PSpice instruction had not an effect on academic achievement according to a group type. However, these instruction had an effect on the following sub-domains; the psychomotor domain. Second, PSpice instruction had not an effect on academic achievement according to a studies level. However, these instruction for middle and low level students had an effect on the cognitive and psychomotor domain, and for middle level students had an effect on the affective domain. Third, PSpice instruction had not an effect on shortening of a training requirement. However, this instruction for low level students had an effect on shortening of a training requirement. The study results of simulation instruction was chiefly efficient in the psychomotor domain. We could know that simulation instruction is efficient as went to a low level students than an upper level students. Thus, We may make the study effectiveness in various instruction method.
