Pl ignore the first pdf attachment. Got in by mistake.
Pl see attached approach to non-dissipating current sense using NVE sensor. This requires the selection of opamps appropriately.
Will appreciate any suggestion to make the circuit behave better as a current source to bias the sensor and the differential to single-mode conversion opamp.
The current sensed is the primary side current of an LLC stage switching at 200kHZ to 400 kHz. It is rather fast s/r
thnx
