Power Supply for Home lab?

mudz
mudz over 9 years ago

Hi,
I am starting this year with different projects. Indeed, I need a power supply which I felt for so long is the main missing component in my small home lab. Currently, I am using PC SMPS, Transformers, and different adaptors to power up different projects and kits.
Many times I felt need of a variable power source but I did that with two different power supplies, but it is time consuming. And many more things to say but its just a waste of time to write and for yourself to read...... Now Its too much and I'm going to build one good power supply. Previously I'm fulfilling my power supply needs by using a adaptor and then using a voltage regulator(7805, 7809, 7812, LM317..) afterward for my projects.
So, what do you suggest?

Also I'm going to include few more additions to it like function generator, power consumption meter.
So what do you suggest what will be the best thing to make a good power supply?

An IC?

A Microcontroller? like PIC

Just build a box consisting a transformer/adaptor with voltage regulator and few pots?

Do tell me which will be better to use? A microcontroller or IC available in market for specific task for example Function generator IC? I'm confused should I go with a microcontroller and make my own program to do these tasks or should I buy an IC for individual task and then using a controller to control all?

    One more question: Linear Power Supply or Switch Mode Power Supply?
    Depends? I may consider doing some business with it as well?
    My plans are to make it:
    1) less bulky/weight
    2) Compact

    3) portable

    4) Stablility with accuracy

    5) much Cheaper than market solutions

    I believe all those Cell/smartphone/Tablet Chargers are Switching Pwr Supplies. They are cheap b/c of your first Three points. Economies of Scale. Our

    "One(ies)-Two(ies)" Switchers will never achieve that Level. My interest in SPS (Switching Power Supplies) is more IC (intellectual Curiosity) than a "want" to build such. That is why I mentioned that I am waiting for that MOOC course at www.coursera.org to be offered again. The one about Switching Power Supplies.
