I have some question reference design PMP9204 for Transformer.

I have taken transformer design in webbench .How much number of wire use in secondary winding.

Hi Vishwanath,

I have asked the original designer to take a look at this question. Please give us some time.

Also, can you clarify what you mean by "number of wire" are you asking about the wire guage, or number of strands?

Typically we work with a transformer vendor and don't have the exact construction details.

Thanks,

Robert

wire guage, or number of strands in one wire also are given datasheet as per attachment.

I show the photo mean by "number of wire"

Hi Vishwanath,

I am sorry, we don't have that information, that is usually decided by the transformer vendor and they don't like to share those details.

Thanks,

Robert

Hi Robert

I am not say to you you will share me renoco transformer details.

I have download transformer data in TI Web bench I have marked attachment picture.

Can secondary side 3 wire use of 26 AWG.

What is meaning Triple Insulated Secondary.

Hi Robert

Please reply me above thread.

What is meaning of Triple Insulated Secondary 26.0/ 5.0 /Counter Clockwise

Hi Vishwanath,

Sorry for the delay. Triple insulated wire is a type of wire that is used for safety purposes, it has 3 layers of insulation. 26 refers to the gauge of the wire and 5 is the number of turns.

Thanks,

Robert

I have attached two Photo. This type has 3 layers of insulation wire.

Vishwanath,

I understand in your picture that there are three wires. That is just a coincidence, triple insulated wire has to do with the layers of insulation.

In general, the transformer design can use more strands on the secondary to help with AC losses or to reduce the amount of DC resistance too.

I am not sure what your question is above.

thanks,

Robert
