Transformer Tutorial
- Series - Parallel Review
- Introduction to Rectification and Power Supplies (PSU)
- Please read the chapters and draw the schematics (detailed below) - to be handed in next class. We we then explore how each rectifier works and why it is used.

Read the chapters relating to POWER and POWER SUPPLIES
Ch. 17: pp 265 - 282 Ch. 18: pp.286 - 299 Ch. 19: pp. 315 - 321 Ch. 20: pp. 325 - 336 Ch. 21: pp. 337-348 Chapter-17: If you are building a studio and need to determine the amount of power that will be consumed, then this is required reading.
Chapter-18: If you've ever gone on a blind date then you should check out this informative chapter on Impedance matching. It's particularly applicable to those building mic preamps and power supplies.
Chapter-19: Semiconductors are not part-time Light Rail engineers, but instead are those solid-state devices that were developed by Bell Labs and are the reason we can have cell phones.
Chapter-20: Diodes, the most basic of semiconductors, only pass current in one direction. This is useful when converting AC-to-DC, illumination (Light Emitting Diodes = LEDs) and clipping (fuzz boxes).
Chapter-21: Supplies, Supplies, Surprise! Now that we know how to convert AC to DC, it's time to dig in and build one to power our project.
Below is the mockup and below that is the layout I did using Front Panel Express.
