I'd try the Three-Phase Semi-Bridgeless PFC Topology Using UCC28070-Q1 (Analog IC).
The principle is using the isolatedhalf sine wave…
Part Number: UCC28070-Q1 Hello, Team,
Our customer plans to switch from a current transformer (CT) to a shunt resistor + differential circuit detection as a current sensing method used for CSA and CSB.
What kind of things do we have to take care?…
Part Number: UCC28070-Q1 Hi Team,
One of the customer is currently using UCC28070-Q1 for an interleaved PFC boost converter. They are using 2 current transformers in each leg of the PFC similar to App note figure 3: https://www.ti.com/lit/an/slua896…
Part Number: UCC28070-Q1 Other Parts Discussed in Thread: UCC28070 Hello,
I am currently working on a PFC with following specs:
230VAC input
425V output
P_total=8kW equally shared between two PFC-controllers (4 interleaved phases with 2kW each…
Part Number: UCC28070-Q1 Other Parts Discussed in Thread: UCC28070 Hi,
I was designing a Interleaved PFC Boost Converter with a power rating of 3.5kW. Is it possible to modify the current cense circuit by replacing the C.T with a current sense resistor…
