Electronics II and Lab – Week 8 Lab

Regulated Power Supplies

INTRODUCTION

Describe how the shunt regulator, shown below, works.

Assuming V_Z = 5.73V, calculate the V_out, I_S, I_L, I_C .

EQUIPMENT

List all devices and meters

1 potentiometer 50Ω

PROCEDURE

Using Multisim construct the circuit.

Replace the load resistance with the 50Ω potentiometer.

Vary it from 0Ω to 50Ω. For each setting of R_L, measure V_out and I_L. Record your measurements in the table.

RESULTS

	Set RL	Measure IL	Measure Vout
1	0Ω
2	10Ω
3	20Ω
4	30Ω
5	40Ω
6	50Ω

Discuss the results.

What are some application functions for this type of circuit?

CONCLUSION

· What did you learn?

· Rules for lab submissions:

· The lab document must be a Word document.  PDF files are NOT accepted.

· All screenshots must be included.

· All Multisim screenshots must include the date/time stamp. See TOOLS AND TEMPLATES for the procedure to display the date and time.

· Any and all Multisim files must be submitted. 

· Any equations used must be typed in Word.  Copy and paste of equations from outside sources is prohibited.

· No graphics are allowed in the Word document other than screenshots of circuits from Multisim and hardware if applicable, with the date/time stamp.

· The lab template should be used.  Specifically, it is brought to your attention that a summary MUST be provided explaining the results of the labs, the relationship of the results to expected results, and any challenges encountered.

· Hardware portion of labs should include screenshots of the assembled circuit with your name and student GID number written on paper next to the circuit. There should be screenshots of the instrument readings with the date and time stamp on lower right corner clearly shown. See example below.

Any violation of the submission rules above will result in a grade of 1.
