Push-Pull Center tap forward(buck) converter

push-pull forward tutorial

Hi...

In our project we want Full Bridge Push-Pull transformer. I tried to search online but could not find any proper tutorial for designing the one. Hope you guys will give some hints. I have allready made it and test it. But there are few lacking in that. The output voltage doesnot go above 25V and output having more ripple etc. That is why I require to study more about this type of transformers or converters.

Specification:
8V to 16V DC input to centre tap primary. And other ends will be driven with pulses from microprocessor 18F2420 by the MOSFETs. The frequency of the pulses will be above 24Khz.
We want output of 30V DC and 20A max on the output(using full bridge).

Please let me know if any link or website for studying this...about formulae etc...

Thanks in advanced.....

Actually we have the same design!!! A personal advice, you can read or have a least a book of keith billings, switch-mode power supply handbook!!!

It has a good design sample, I think you can used it..


Cee yah!!!
