Part Number: UCC28070 Tool/software: Hi Ulrich,
starting from the sketch designed by you, I made an LTSpice simulation to verify the functionality.
Based on the values given the VINAC signal do not reach zero level when in DC mode (see the red circle…
Part Number: UCC28070 Hi Ti expert,
I am using Excel calculation for interleaving PFC ,while doing so optional Freqency dithering magnitude,frequency dithering rate
Could you please explain about this?
what could be the range of frequency to be entered…
Part Number: UCC28070UCC28070 is used in interleaved PFC boost converter in continuous conduction mode. If there is a power interruption for few seconds will the switching MOSFET be short?

Part Number: PMP8740 Other Parts Discussed in Thread: UCC28070 Hi Ti Team,
I am using UCC28070 IC for EV charger application,P=3.3KW,output is 400V
I have one doubt,is DC blocking capacitor is required for transformer primary side?
i have seen all reference…

I'd try the Three-Phase Semi-Bridgeless PFC Topology Using UCC28070-Q1 (Analog IC).
The principle is using the isolatedhalf sine wave…

CH1:PFC output voltage,CH2:LLC output CH3:Input current CH4:PFC MOSFET VGS
Hi TI E2E
When the output reaches full power instantaneously, the occasional drop in PFC voltage may occur.
The attached diagram reveals that when reaching…
Dear Ulrich,
I have the good news that my problem is solved. When the Magnetizing inductance of CTs is increased, the voltage at ISENSE pins and the current through Ids are almost the same. My input current is so "sine" and the spike current at Zero-crossing…
