## Discussion on ASITIC and On-chip Transformer Design

You do an serious error. Primary and secondary inductances are not calculated as you mentioned. The inductance values are depending on frequency of interest. At least minimum values of inductances will define minimum frequency that you may use for the transformer. For more information look at equivalent circuit of a transformer.

## Transformer design for high power DC DC converter (help)

Hi, For your kind of power requirement the larger U core U 141/78/30 can be used , or you can stack 4 E 55 cores, a special bobbin is required to do this. Any way a 5 Kw transformer is trickey to design because of the cooling requirement. a forced air cooling will be required.

## RF transformer design

Hello all, when designing a class A&AB RF amplifiers (for example for the range from 3Mhz to 30Mhz) using a transformer to match the laod to the transistor output impedence, the ratio of the turns can be easly calculated, but: Q1) how the actual number of the windings is calculated? Q2) in case the primary of the transformer is tuned (...)
