ETron Circuit LabsOutput (+)Lab 18DC to DC Power SupplyObjective:In this Lab you will build a DC to DC Power Supply circuit that will adjust the bias allowing you to obtain a range of output voltages.Step 1 – Take InventoryUsing the Parts Inventory as shown on the right under the “Here’s What You’ll Need” section, place each part needed for this experiment on its corresponding drawing. Observe the schematic symbol for each part. Make sure that you have all the parts ready before you begin Step 2.Step 2 – Build the CircuitUsing the Schematic Diagram and the picture of the completed lab, build the lab experiment with the electronic components. Use the “Check Your Work Here” Box to verify that your wiring is correct, and then proceed to Step 3.Step 3 – Do ExperimentTheory:This circuit is a transistor with a potentiometer in place to adjust the bias on the base/collector circuit.By adjusting the bias with the potentiometer, you are able to get an output from 0 volts DC to 9 volts DC.Output (-)34
