Where Npri is number of primary turns and Nsc is number of secondary turns. You may also need to use LC filter to harmonics or AC components from output. We need to use full rectifier to convert it into dc of 310 volt. The output of ferrite core will be always high frequency square wave of 50 KHz. I will try to write separate article on it. It is beyond the scope of this topic to tell how to select ferrite core according to power rating. We are using ETD39 ferrite core which can handle 250 watt.

We want to step up dc voltage from 12 volt 310 volt.

We are using push pull topology for this design. For example we want to design a 250 watt boost up dc to dc converter. Push pull topology ferrite core turns ratio calculation with example In other words, push pull transformer have two times primary turn than full bridge transformer. The only difference between push pull topology and full bridge transformer design is that push pull ferrite core transformerrequires a center tap in primary winding. Turns ratio calculation formula and concept remains same for both topologies. Ferrite core turns ratio calculationįor example in boost up stage we have two options to use from power electronics converters, push pull topology and full bridge. In this article, we will learn how to calculate turns ratio of high frequency ferrite core transformer with examples. For example in isolated buck converterit is used to step down dc voltage and in isolated boost converter, they are used to step up dc voltage. Ferrite core transformers are also used in isolated dc to dc converters to step up or step down dc voltage. They are used to boost up or step up low dc voltage of battery and other dc sources like solar panels. High ferrite core transformers are used in almost every power electronics circuits like inverters and pure sine wave inverters. In this article you will learn how to calculate turns ratio of ferrite core transformer for high frequency switch mode power supply inverters.
