UCC28065: two rectifier connect with different chanels of UCC28065 separately

user4681182

Part Number: UCC28065

Because the AC input current is high , so the filter size is too large.

Customer wants to use two filters and two rectifiers to connect with the two channels of the UCC28065.

Is such an idea feasible?

What are the risks?

thank you for your support!

Hello,

Could you explain to me what you mean by the filter inductance is too high?

In regards to running the boost inputs off of two different bridges as you have in the diagram above, functionally that will still work.

Is the customer trying to do this to use a lower power diodes for the bridge rectifier?

i mean the volume of the filter is too large.

customer wants to use smaller filter and the bridge rectifier.
