Hello,
i would like to construct a circuit measuring the current passing through the load of a buck converter i designed. So i constructed the circuit shown below (from internet sources) in PSpice:
This circuit operates normally giving desired result(the voltage on the output of LT1498 gives 1:1 the current passing through the load and RShunt).
But after changing the topology(for some reasons) of the buck converter the circuit doesnt operate correctly as it doesnt measure correct current.
The new topology is :
Could anyone help on this?
Thank you.
