This is an assistant calculating tool for transformer parameters,which could work under the frequency of 50Hz and power of 1000W.It is very useful and practical for those people enjoying DIY transformer. With such an assistant calculator, you do not need to calculate by yourself.
This gadget is easy to use, even a novice can handle it quickly. It could improve work efficiency while reduce the possibility of making an error. Here are some tips for how to use it:
Firstly, input the variables of the cross sectional area of a chip or transformer power(once any of the variable is input, this tool will automatically figure out another parameter based on empirical equation). Secondly, input three parameters from voltage, frequency, magnetic flux and number of windings .Finally, click the calculating button then you can get the missing parameter. With a help button, you could open a prompt interface, which help you calculate the magnetic flux of chips with different materials.
