Exp 4: LM317 Rectifier power supply unit 1) Circuit Figure 1 shows an advanced version of the PSU. The closer you are to this design, the better your project will work D5 Protection diode Fuse OUT 2 TR1 12V-0-12V 1.5A INPUT 220V AC C1 C3 1uF Vout R2 10k Figure 1 LM317 PSU The values of figure 1 is for clarification only. Your circuit may have different values. 2) Design instruction Your OUTPUT voltage must be THE LAST NUMBER of you STUDENT NUMBER. E.g.: 22123456 will give 6V as the output. Those with a "0" as last number - use 10V The values of C1, C2 and C3 are to be replaced by that issued by the lab technician. The fuse is completely optional. R1 and R2 must be of such a value that it will give the required output voltage. R2 does not need to be a variable resistor if you have a fixed single output voltage The technician will provide you with most components - you have to tell him what your resistor needs are based on your design 3) Use SMATH for all the calculations 4) Use SImetirx or Multisim to simulate your design 5) include all the graphs and values at the various headings in the report 6) Take a photograph of your construction and include it at the appropriate heading in the report 7) Ensure you bring your design noted to the lab so the technician may know what your expected output voltage will be.

In other words: You decide and provide your own method of assembly of the circuit D1 D2 03 C2 100uF IN 0.1uF LM317 9 ww R1 250e
