Hello,
I'm working on designing a 3 kW PSFB and could use some help with selecting the current sensor + amplifier for the secondary side load current sensing.
A few relevant specs about the system -
- 3 kW output (3000W/12V = 250A output current)
- 100 kHz switching frequency
- MCU control
Based on this white paper, it seems like a shunt would be better in terms of accuracy, max temp, and bandwidth capability. I'm working on selecting a current sense shunt amplifier and was wondering if you have a recommended part here. I'm not sure what the bandwidth requirement is here, but I imagine it may be a function of switching frequency? If you could help with that as well, that'd be great.
I was looking at the INA180 datasheet and had trouble identifying what the maximum input voltage is without clipping. Where can I find this information?
Thanks!
