본문 Electric Circuit Experiment Pre-Report Chapter 4 Various Diodes and its Properties Department Year Studnt ID Class Team Name 1. junction diode ① What are the other applications of diode in electrical devices. 1) Half wave rectifier The (ideal) diode conducts for vi >0 and since Rf =0 , V0 is almost Vi For vi < 0 the (ideal) diode is an open circuit (it doesn't conduct) and V0 is 0. 2) Diode Clipper Circuits When the diode is off the output of these circuits resembles a voltage divider If RS << RL , The level at which the signal is clipped can be adjusted by adding a d.c. bias voltage in series with the diode. ② Using approximation 3 in fig 4-3, draw equivalent circuit of junction diode r _ B = V _ F -V _ D over I_F ③ Explain the reason why there is difference between measured value and calculated value in table 4-2. We can calculate the value of the resister by using gradiant btween two point is inverse of resistance value. But that gradiant is expotential function at the real diode. So it can be error in there. The value of the resistance is different by the value of current and voltage. Specially, at 0.6~0.8 voltage, there are much change of gradiant that have much difference between measured value and calculated value. fig. 4-1 measuring diode order V_AK I_D R of diode 2 0.7V 5.9mA 하고 싶은 말 좀 더 업그레이드하여 자료를 보완하여, 과제물을 꼼꼼하게 정성을 들어 작성했습니다. 위 자료 요약정리 잘되어 있으니 잘 참고하시어 학업에 나날이 발전이 있기를 기원합니다 ^^ 구입자 분의 앞날에 항상 무궁한 발전과 행복과 행운이 깃들기를 홧팅 키워드 결과, 기초, 실험, 전기, 기초실험, 전기전자
