Tool/software:
Hello all,
We are designing a 1.5kW PFC using UCC28070 with universal input, facing all sorts of challenges in selecting a current transducer with transformers ( like their limited avialibitiy , sizing, prices, ...) we came through a solution TIDA-01390A(001) which uses shunt resistors and opamps (much-preferred way) for current sensing, however we realized there are many challenges for this, in any case in the schematics of TIDA-01390A(001) what we don't understand is the presence of those series inductances/trasnformers of L1,L2 and L3,L4 per each leg, can we know what are those?
Thanks
MM
