I wrapped the smps switching transformer with a copper tape to reduce the emi. What would you suggest the grounding procedure.
The tape should be Grounded to DC directly or
it should be grounded...
I would like to do some LOAD test for 12V, 24V and 48 Volt SMPS. Is there any Schematic available to build a MOSFET based Adjustable DC LOAD
OK................... How much it will cost ? (Stereo - Two assembled PCBs)
i am trying to design a 5vdc 1amp isolated smps using VIPer22a ic from st microelectronics. I have viper design tool that designs a circuit. but i don't know much about the circuit. How does the...
Sorry for my bad English.
Iím looking for some good smps schematic to build some and I found this on internet. In this schematic input voltage is 12v and I want to connect 220v and donít...
My Oscilloscope has started giving some problems.Its a Tek 2465.
Showing error 45. Unable to read out .It will need to be fixed before proceeding
I do not think you need totem pole drivers.
I have tried car battery but same issues.
Does input mosfet requires totem pole drivers?
A car battery will have lots of current. Give it a try and see if it gives you your 5 volts.
The post on STM32 is ready here http://microcontrollerintro.blogspot...ontroller.html I will add another post
I am doing this as an experiment and experience .I would like to build bigger 230v smps later after learning through this.
This smps will
What are you trying to do here. Are you making this for fun. Do you really need this to work for a long time. Do you really need 30 amps out.
P = I x E
30A x 5VDC = 150 watts
150W / .7 = 214W
I = P/E
214W / 13.8VDC = 15.5A, your supply
I have used fairly good enough heatsink.
Here is the attached picture of completed board.
My test power supply is a
Your output rectifier MBR3040 will burn out fairly quickly at 30 amps. It is rated for a maximum of 30 amps and after pwming it is probably only good
If someone want this e-book,just send me the mail,it's free of course.It's copyrighted.
I am trying to build a 12volt to 5volt 30 ampere dc-dc smps.
I have used Sg3525 as switching IC and IRF3205 mosfets and MBR3040 output diode....
Hi there. I have always been told that traditionel power supplies with huge transformers and large electrolytic bridges is much more Space consuming...
I have made a post at http://microcontrollerintro.blogspot.com/ for anyone to get a general idea of how to deal with microcontrollers in general and...
Hi everybody !
First post in this nice forum I've just discovered !
Here is my problem : my subwoofer can not turn on.
This is a Focal Cub...
