Part Number: TIDA-00961
Hi, recently i have studied about totem pole pfc.
I am currently working on totem pole pfc.
I have a question that I don't understand during circuit analysis.
As you all know, the totem pole is a topology that uses only mosfet instead of a diode bridge.
However, you can see that there is a diode bridge as shown in the photo below.
At the schematic diagram of the other totem pole pfc, that D105- 'gbu4k' device always exist.
Actually, I think it would be okay to operate without the device, but I wonder why it is included.
I attached the schematic of TIDM00961. Thanks.SCHEM_TIDA00961.pdf
