half bridge transformer design amazon

Hi,
For the 200W use a half bridge forward converter and for the 1000W one use a full bridge forward converter. A flyback design is just possible for the 200W but this is on the limit so I would not recommend it for a first try.

Start here for downloading the magnetics design software:
http://www.mag-inc.com/

Then follow this link or the link marked magnetics builder on the Magnetics Inc homepage for reference circuit designs and design software.

I hope this helps.
There is quite a lot to switch mode PSU designing, so expect a few failures early on and be very very careful as part of a SWMP is mains live, use an isolation transformer for the initial test stage if you do not want to risk death.

I would also recommend that you buy a book such as Practical Switchmode Power Supply Design by Marty Brown.

Good luck
Bob.

switch mode power supply 48v 1000w

Hi,

Try Amazon, the price seems to have increased since I got my copy however.

I forgot to mention it previously but the UC3526 or a similar TI device is a good PWM contrroller for your needs. See the TI website or search the Internet for info.

Cheers.

High wattage SMPS

Hi,

DrBob13 had mentioned about powerEsim, it new site is:
https://www.powerEsim.com/
You can go there to find both Two-Switch Forward Converter and half bridge forward converter and do simulation there.

Hopes it helps.
