The space vector modulator generates sample timing signals based on the power inverter state. The IC integrates the A/D converter and amplifier to sample the voltage across the shunt ... WebNov 5, 2015 · A quick reminder, low-side current-sensing is where the sense element, or shunt resistor, is placed in series with the load between the load and ground ( Figure 1 ). This is the most common method to measure current. Simplified circuit diagram configured for low-side current-sensing using a current-sense amplifier.
WebIn the above shown current sense resistor circuit, we can observe how a resistor is connected in a current-carrying lane & how the drop of voltage across the resistor can be measured through a current sense amplifier. The shunt resistor’s power dissipation can be simply determined through the following formula. Power dissipation (Pd) = V x I
