Hi,
We have a 100W PFCd Boost then Two Tran Forward converter (40vout) which runs in a hot room in our growth plantation. Its 90degC in there.
We need it to keep powering for 200ms after any power down.
So we need a big bank of Alu poly caps on the 40V rail.
Is there any problem for us with 125degC rated Alu Polys and 90degC ambient?
There's no fans, its just screwed to a big metal wall.
We believe Alu Elec is no use due to temperature, Film is just too big for us.
Are there any others, even if very expensive, that could do the job?
