Single-shunt current sensing amplifying network

The STEVAL-IHM036V1 motor control demonstration board is configured to run in single-

shunt current reading configuration modes which is suitable for using field-oriented control

(FOC).

Current sensing networks were the chosen configurations with the shunt resistor together

with an amplifying measured voltage with an operational amplifier integrated into the

SLLIMM™ module STGIPN3H60.

Details of the FOC current sensing reading configuration are shown in Figure 8. In this

configuration, the alternating signal on the shunt resistor, with positive and negative values,

must be converted to be compatible with the single positive input of the microcontroller A-D

converter used to read the current value.
