planar transformer use in TFS design
Posted by: akasapa

I want to use a planar transformer (not wire, nor foil but pcb type) in my 28VDC 10A single output PS design with HiperTFS family. Does PI database have such a design example, guide or AN?

which product should i use for 115V 400Hz input 28V 10A output with planar transformer and without PFC circuit?
HiperLCS (LLC) running at 300+ kHz.
What is the input voltage range?
input AC voltage is 115VAC 400Hz within +-10% limit.
Do you have a hold-up time requirement?
I do not have a hold up time requirement.
Then the minimum input voltage for the LLC can be as high as 125 VDC.
Planar transformers are not recommended for 66 kHz designs.
They would be appropriate for 250-300 kHz. Look up our HiperLCS (LLC controller) product for that.
