5 kW two-channel interleaved CCM PFC EVAL board

IKW40N65WR5, IDW60C65D1 and 1ED44175 in high frequency PFC application

System design

Because UCC28070 already has an integrated output over voltage protection via the continuous monitoring of
V

VSENSE,

the intput over-voltage protection and under-voltage protection in this converter are implemented by an

external comparator, both of which are also connected to the SS pin of UCC28070.

Auxiliary supply of EVAL-PFC5KIKWWR5SYS

Figure 10 depicts the auxiliary supply of the evaluation board, supplying the voltage to the controller circuit, gate
drivers and cooling fans. ICE5QSAG [2] is a QR mode controller for soft switching operation of Q5, it helps to
