General computer PSU diagram please?

05-23-2011, 04:16 PM

Hi guys!
Thanks for all your great contributions. I enjoying looking through these forums and I have learned a lot. I was wonder if anyone was willing to get a picture or pictures from a your run of the mill computer power supply and label what everything is (to the best you can).

I've read though the FAQs and it was helpful, but I have trouble visualizing them on the PSU.

AC Filter (I already know but may be helpful for others)

Rectifier & Filter

Inverter

Pulse Width Modulator

Output Rectifier & Filter

Voltage Sense Amplifier and Protection

Standby Regulator

PI filter components (ie input caps/ output caps, inductors)

I tried searching but couldn't find anything. If you know of any links that could help, that would be awesome!

Thanks again! Any contribution would be much appreciated.

Dynacord powermate 1600 block diagram.

by hs5424

Hi All,
I obtained a schematic diagram for the above mixer but I am wondering if a block diagram exists as I am trying to fix a problem in the protection circuit which I find a little confusing using a circuit diagram only. In the good old days the workshop manuals always had a block diagram with a circuit discription. Very useful for fault finding.
The protection light is perminently on. The right sode has a -80DC on the feed to the speaker, hence the protection led on. I have removed all the O/P transistors which checked out OK. I tested all other transistors in circuit which seem...

Help with boom box modification

by Califauna

Hi, this is more of a project help request than a troubleshooting question. I hope I can post it here.

I have a W-King D8 Bluetooth boom box which I'd like to modify with some external speaker output jacks and some buttons to switch the internal speakers on and off.

From factory the specs of the boom box are:

-Power Input: DC 5V
-Speaker Output Power: 2 x 25W ( confirmed by Youtube channel Hartdegen review as 12.5W RMS per channel)
-Drivers:
-2 x Woofer, 70mm, 10Ω, 70mm,15W
-2 X Tweeter, 8Ω, 30mm,10W x 2

I'm looking for the wiring diagram for led monitor model DHI-LM19-L200

by gabri2211

hello everyone, I'm looking for the wiring diagram of this led monitor.
the model is DHI-LM19-L200, but I think that any other diagram of a DAHUA monitor could be equivalent.
I really hope that among you someone can help me to repair this monitor, the screen is black, it doesn't seem like a backlight problem.
I see the presence of 12 volts, 5 volts, but without a diagram the repair is very difficult.
thanks to those who will answer

Bridge rectifier identification part number KPB305G

by Steph.hen

Hi all, a newby question about a bridge rectifier I'm trying to identify.

I'm in the midst of reparing a battery charger in work which went pop, The bridge rectifier has shorted and took out a couple of other components. The rectifier in question has a part number KPB305G, and it looks like it's obsolete. Does any one know what I could replace it with?...

Finding proper replacement rectifier

by unimatrix93

Hello everyone,

I'm trying to fix up my battery charger. Where I found a dead schottky rectifier.

This is the dead component PTR30L120CTF:
PTR30L120CTF datasheet(1/7 Pages) PFC | 30A 120V HPTR Schottky Rectifier (alldatasheet.com)

And I have a spare 30CPQ150:
30CPQ150 datasheet(1/5 Pages) IRF | SCHOTTKY RECTIFIER (alldatasheet.com)

Can I use this diode as a replacement or if not, can you recommend me a proper replacement?
I cannot find the exact unit anywhere besides aliexpress and such.

Thank you guys!
