Hi All

I am in the process of designing a push pull converter and wanted to enquire how you go about determining the number of turns on the primary and secondary side of the centre tapped transformer I know the turns ratio, can anyone suggest the calculation or a rule of thumb when selecting the number of turns on the primary and secondary side this is a boost push pull converter. Is it just a case of letting the primary side =1 and the secondary what ever value N you wish to boost by, I assume the primary side will require more turns. Any suggestions or help will be greatly appreciated.

Kind Regards

Hi,

I'm not expert when designing DC/DC converters, but once I was doing a research about the design of a push pull topology and found this post very helpful: http://tahmidmc.blogspot.com/2012/12/ferrite-transformer-turns-calculation.html It explains the calculation of required turns.

Hope it helps.

Ok thank you

 

The calculator is probably the best approach for you. If that doesn't work out, just use 1 to 2 turns per volt, then based on the necessary wire size select the appropriate core & bobbin and gap.
