1. Title:     Rectifiers and DC Regulators

2. Introduction

The goal of this lab was to be familiar with the Rectifiers and DC Regulators and to be able to design a DC power supply.

3. Materials and Methods
First, for task 1. we built the circuit on LT Spice to find out the built-in potential. For task 1.2 we set the build-in potential to .6 Figure 1. Intask 1.3 and  we used a 1N 5767 and 1K resistor to set the same circuit Figure 1.3. In task 2 and 3, we simulate the circuit given on LT Spice and on the breadboard(Figure 3). For 3.2, we used  ziner Diodes and a resistor to managed the voltege Built-in to be 10. LT Spice was used and a breadboard(Fihure 6). Finally, for task 4 we used the circuit given to make a voltage doubler in LT Spice and breadboard.

5. Discussion.

In this lab we got only half of the wave being rectifying. We modified the built-in potential to .6V and we showed similar results from the breadboard built. In task two we got a nice line as a signal, closed to beind a DC signal by using the diode and capacitor(low pass). In task 3 we simulate the circuit given and understood how the diode is trying to change the signal from AC to DC on both sides. On task four our circuit had 2 zener diodes that regulale the AC signal to become closer to DC and also protect the circuit from voltages larger than 10V. And for the last task, we succesfully create a hogh-DC voltage using a voltage doubler using a high pass and a low pass diode and cap systems. We only repeated this two times for the safety reasons.
