Hi Denny,
Thank you for reaching out. Yes this can be supported by a boost controller or converter in the inverting buck-boost configuration like shown in the following ref design:

Obviously the ref design has a…
Hello Sachin,
Some of the distortion seen in the input current (THDi) is due to the distorted input voltage (due to building distribution and Variac impedances), but I believe that most of the THDi comes from inductor current operating in discontinuous…
Hi Delta,
No matter what method is used, if the output voltage is lower than input, the boost topology cannot meet the requirement. Even set output voltage lower than input by changing REF voltage, the boost topology will limit this voltage transfer…
Hi,
xiaoxiao xiaoxiao said: During the test, the PWM duty cycle is 0 or the maximum value set for the current loop.
The PWM output(light blue) is not clear to identify. But anyway you are saying the current output is not as expected.
We have…

Hi Experts,
I am trying to Mix assembly with C, but for some unknown reason, the assembly functions aren't seen by the Linker. The thing I am trying to do is to…
Hi Prerana,
Current limit is an averange one.
In boost mode, you can treat this current limit as input current limit and as output current limit in buck mode. in buck mode, we can increase the output current slowly when the current limit is trigered…

TI Team,
You offer 2 very interesting ref designs, and for that I thank you! However, do have a few follow up questions:
1)TIDA-010933: I see that…
I assume the system blocks upload of .xlsm file type.
Please check if below can help.

Part Number: UCC28180 Other Parts Discussed in Thread: UC2854B Dear Sir,
We are developing a boost-PFC converter. For the generation of the switching pulses currently we are using the UCC28180.
While experimenting for a power level of 1600W, we are…
Part Number: TMS320F280039C Hello, I am investigating what total value of reference current could be set summary in Id and Iq controllers for InstaSPIN solution (ecompressor example), with consideration of max limit of total current.
I found out, from…
