3 shunt low side vs 3 shunt 'in phase' current sensing
Forums:
Hi,
I understand that when moving from 4.12 to 6, the current sensing method was changed from 2 shunt 'bottom side' to 3 shunt 'in phase' .
Current sensors for in phase applications - specially for high voltage application are pretty expensive, and the only credible option for me seems to be the ACS758 or variants that other members seem to be using.
Questions:
- Is there any benefit of 3 shunt 'in phase' sensing over 3 shunt 'bottom side' current sensing for FOC ?
