Unformatted text preview: EE 201 Lab9 Tian Gu Code:721 Team partner: Tielong Su Chaojun Zhang Introduction : In this lab, we understood the transformers and after that under rectifier and how do they supply voltage. And we knew how to design a circuit which delivers three outputs. The Input Section of the Power Supply We built the circuit first. According to the Lab guide, we need a load which with 8.6 k resistance. But we cannot find any resistor like that. So we picked a resistor with 20000 resistance instead. Here is the input signal of the rectifier: According to the guide, we will have the DC output at this point with a very large amount of ripple . And here is what we got, Then we smoothed the ripple with creating a filter. The Output Section of the Power Supply: We simulated the initial circuit with PSpice and came up with the following basic initial circuit....
