AE-252: Week-4
POWER SUPPLIESBefore coming to class on Monday you should have read the following chapters as they relate to your need to understand power supplies - that's what we'll be building.
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.
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.
RECTIFICATION
No matter what this word brings to mind, it's about AC/DC, not the band, but the process of converting the latter to the former.REGULATION
It's not what you eat for breaksfast, how much fiber's in your diet or how the gov't mismanages everything, but it is about how a nice stiff power supply can make your day. click hereDA FEWCHA
Something to look forward to, click on the image below to find all the preamp kit plans...Below is the mockup and below that is the layout I did using Front Panel Express.
