Motivational Design Problem:
Here, we were to design a system which consisted of an unregulated power supply connected to three loads in parallel. The objective is to be able to design a system which stays within operational parameters no matter how many of the loads are on or off.
Design Parameters:
We are given that all three loads have a resistance of 1kOlms. No matter what combination of loads are on or off the the voltage must remain between 4.75V and 5.25V.
System Model:
Pictured is the model which we developed. It consists of a voltage supply set to 6V connected to a variable resister box (VRB) in series set to 55Olm. The VRB is connected to three 1kOlm resisters in parallel which are in connected back to the voltage supply. We measured the current through each resistor as well as through the voltage supply.
Results:
The circuit operated within the desired parameters.
