PFC UC3853(a) max line Frequency

Other Parts Discussed in Thread: UCC3817

Hi,

i have to design a PFC for an input range of 0-400Hz line in frequency.

Is it possible?

Which part assigns the maximum frequency i can use?

 

Greetings and thanks in advance

    Most PFC controllers will work with a DC input.  Most of TI's PFC controllers have been tested with an input frequency of 47 to 63 Hz.  All of the PFC designs that I have done are in the 47 to 63 Hz range.  I do know of some customers using the UCC3817/8 PFC controllers for 400 Hz line applications.  I have not heard of any customers using the UCC2853(a) for these applications so I am not sure how it would work.

    I went to APEC in 2006 and there was a good paper titled “Current Phase Lead Compensation in Single-Phase PFC Boost Converters with a Reduced Switching Frequency to Line Frequency Ratio” written by Konstantin P. Louganski and Jih-Sheng Lai from Virginia Polytechnic Institute.  This paper reviewed how to design PFC pre-regulators for high frequency applications.  They used TI’s UCC3817 controller for their design.  You might want to see if you could get a hold of this paper it may help you with your high frequency design. 0-7803-9547-6/06/$20.00 ©2006 IEEE.
