Rectifier Box
October 31, 2016 - 10:22am

So I have a project I need some help to get started. Does anyone have any idea how to go about it. My friend was thinking of making it a touch screen 

Objective

 (MDCPS) system is interesting in developing an educational tool to teach rectifier circuits to magnet high school technology students. While they plan to initially pilot the program in a few classes, if successful, the intent would be to expand this project to thousands of classrooms across the country. The school system is currently soliciting prototypes from private companies, and your boss has assigned your team to the task.

 

While the initial bid is only worth a few thousand dollars to your company; if selected and your design proves successful – this project could result in a no-contest bid to create these boxes for the entire country which would result in hundreds of thousands of dollars for your company.

 

Project Requirements

The administrators who initiated the project are not technically inclined, so the specifications they have provided are very general and minimalistic. They are expecting the competing companies to take their specifications and come back with a working prototype and manual that will wow them. The minimal requirements for the project are:

 

  1. The final prototype must be a professionally packaged and fully soldered. It must also provide no electrical hazard and be durable enough to take a beating from high school students.

 

  1. The school district would prefer it if an external power supply were not necessary. You can assume that the classroom your box will be deployed in has a standard function generator (input source) and digital oscilloscope (output source). If you do use an external power supply, it must be a professionally UL certified (i.e. if you are taking power from the wall, you must do it with a purchased adapter that is fused and simply plugs into your device). Safety is of the utmost concern for the school district.

 

  1. A manual that fully describes every function that the box performs. This is one of the most important aspects of the project. The manual must detail at a minimum:

 

  1. The parts (with part numbers) that were used
  2. The absolute maximum/minimum amplitudes, frequencies, etc for each function given the parts that you used
  3. Complete Schematics of the system
  4. A sample set of experiments the students can perform using your box with complete simulation results. You can use the equipment in our lab to get a rough approximation of the output capabilities of the function generator, but remember that although you are guaranteed that the school will have a function generator; it may not have the exact same capabilities of the one in our lab. Thus, your sample experiment should take this into account.

Rectifier Box Requirements

The school district is expecting you to use your technical creativity to impress them; however they have provided you a simple example of what they are looking for and come up with a set of minimum ratifications that your device must be able to accomplish:

The box must, at a minimum, perform the following functions:

 

The box must, at a minimum, perform the following functions:

 

F1.Straight pass-through

F2. Half-Wave rectification

F3. Full-Wave Rectification

F4. DC Output

F5. (A fifth function that you design)

 

Please note that the above design is simply an example, and you can feel free to improve upon or design the box in a different manner – but the functionality must be completed.
