Hello
I have given a task to calculate skin loss and proximity loss in inductor. since the current wave is triangular so Fourier decomposition applies.I have already calculated the skin loss by finding ac resistance and using it into I^2*R formula then I am able to calculate skin loss. For...
Hello everyone
We use steinmetz equation to find the corelosses. I have four coils from different suppliers and I want to know core losses in each coil. Problem is that there is no information in the data sheet about the core materials and no flux density, frequency and power graphs are given...
I am writing my thesis in a company and I have to report my professor in every two months. Company has no issues with the procedure/approach but at the end professor has to give me the grade. I do not know what kind of tools needed for direct measurement, I think possible equipment that I need...
No. prof ask me clearly why not to connect oscilloscope probes directly to inductor and observe the current and voltage to find losses. he further said that indirect approah is as complicated as the direct approach so what is the advantage. And I aid I knew only the indirect way but he is not...
HEllo everyone
Currently I am working on a boost converter thesis project and my task is to find losses in the inductor. Its hardware based work.
I have three questions regarding inductor losses
1- For the given coil, core material properties are not given in the data sheets and I also...
Thanks I understood the point. I am also searching for more points in favour of indirect approach so in future if you come across something related please inform me. I will discuss the points you mention with my prof.
Hi thanks for the response. I determine low side mosfet losses in this way
1- for conduction loss, the same inductor current(measured using current probe) flows in the LS mosfet and using rdson conduction losses are calculated
2- switching loss in low side mosfet are calculated by measuring...
Thanks for your quick response. I already gave him the same reason but he was not satisfied. Its my thesis work and if I failed to defend, the result will be deduction in my thesis grade.
I have a question, at this moment I can measure the current at the inductor by using channel one of...
Dear all
I have designed and develop a simple synchronous DC DC boost converter. The task given to me is to find power losses in the inductor of the converter. I choosed an indirect approach for example I measured the overall losses in the converter, then I found the low side mosfet losses...
