Activity 2: The Zener Diode Voltage Regulator R1 V1 1000 E12V DC 10MOHM 330 XMM1 U2 D1 5.955 1N4737A R3. Iko: 100 %: Key=A 12V Multimeter-XMM1 Multimeter-XMM2 U1 DC 1e-090hm XMM2 0.011n 24 V 180.451 mA A V dB A V dB Set... Set... 1. Connect the circuit as represented in the schematic circuit. 2. Ensure the Positive Variable Power Supply and Negative Variable Power Supply are set fully counter clockwise (minimum). Note: The two variable power supplies have been configured so that together they provide a supply of up to 24v. Each providing 12V output. This supply is used to provide the supply (VS) to the circuit) 3. Open the DMM. This displays the voltage VS, but if amps is selected it displays the current through the load (IL). 4. Open the MCM. Channel 1 (Top) displays the current passing through the Zener diode (Id), channel 2 displays the voltage across the diode. 5. Slowly increase Vs by adjusting the NVPS until the diode just begins to conduct current. Record Vs and IL = 0 in the first row of the table. 6. Adjust the NVPS until Vs equals 10V, now adjust the PVPS control until Vs equals 12V, the diode current will increase above 5mA. Then adjust RL until the diode current just returns to approximately 5mA. Again record Vs and IL 7. Repeat this for Vs = 14, 16, 18 and 20 V recording the results in a table as shown below. %3D Supply Voltage (Vs) Load Current (IL) millliamps 24 180.451 12 7.26 14 7.274 16 7.282 18 7.287 7.292 With the given data above, answer all the following questions: Discussion of Results: Conclusion: Assessment Task: 1. As performed, state the differences of a shunt and series voltage regulator circuit. 2. What is the important role of a regulator in a circuit? Why is it needed? 3. Define the main difference between a rectifier diode and a Zener diode? What is their difference in circuit applications? 4. What is the effect of applying negative voltage onto the Zener diode? 20
