Part Number: TIEVM-VIENNARECT
Other Parts Discussed in Thread: OPA333

We are in the process of designing 3-phase AC power supply, input 85 VAC – 150 VAC 47 Hz – 440 Hz. We are using TI Vienna Rectifier PFC circuit design; however, we want to replace part number LTSR 6-NP current transducer with TI floating current sensing circuit, do you have any recommendations?

Hi Neguse,

I don't have a recommendation but I will see if our Amplifier groups can give you some suggestions.

Hello Neguse,

Thank you for your post. I can help you.

We have a few examples that I'd like to share with you:

The first is an example from our OPA333 datasheet - section 8.3.4 on page 21, Figure 30: http://www.ti.com/lit/ds/symlink/opa333.pdf
You may also refer to the following circuit example: http://www.ti.com/lit/an/sboa295/sboa295.pdf
The above circuit is based on a design found here: http://www.ti.com/tool/TIDA-00332

I hope this helps.
