Part Number: PMP40261 Tool/software: Question1:
In the datasheet, it is suggested to use a current transformer in series with the power switch to detect the current, then synthesize the inductor current waveform inside the IC.
But in this way, the…
Part Number: UCC28070 Hello,
Can you provide design files for EMI filters of PMP40261-Bridgeless PFC converter which was previously available in TI.
I have attached the schematic file below

Part Number: PMP40261 Tool/software: What is the purpose of the two diode bridges?Why is it termed bridgeless converter when it consists of two bridges?
Part Number: PMP40261 Tool/software: I would like to know the purpose of the 2 diode bridges at the beginning .Why is it termed bridgeless PFC rectifier when it consists of 2 diode bridges. Bridgeless PFC rectifier is supposed to give a better efficiency…
Part Number: UCC28070 Hi E2E,
Our customer is designing a 3kW charger by UCC28070.
It is used for VIN AC150V~280V input. The Duty-Cycle is setted 0.95 and the frequency is 61kHz.
We found that VIN gradually increases from AC 150V to AC 200V, the…
For 12kW application, you may need 3 phase AC input to distribute the current. I don't recommend to use single UCC28070 for 12kW.
But you can put multiple UCC28070 modules to achieve total 12kW. Each phase say 4kW.
Here is a single phase ref design…
UCC28070 doesn't support interleaved totem pole PFC but there is a AC bridgeless ref design available: www.ti.com/.../PMP40261
but it's not AC bridgeless !
Hi, Juliaa
PMP4311 is very old reference design, there is no such data you required. There is another 800W reference design PMP40261, there are ITHD data for different input voltage and output load. here is link of PMP40261. BTW, PMP40261 is bridgeless…
