Figure 10: Table comparing all results
Based on the results shown in figure 10, we can see that overall, our values were very close to each other. The only difference was the simulated and measured ripple voltage were a little higher than the calculated ripple voltage. This is likely due to the imperfections in the resistors and capacitors. However, the simulated and measured values were so close that we can conclude that the circuit was accurate.
