9.2 Typical Applications
9.2.1 Frequency Inverter Application
Isolated ΔΣ modulators are widely used in new-generation frequency inverter designs because of their high ac
and dc performance. Frequency inverters are critical parts of industrial motor drives, photovoltaic inverters (string
and central inverters), uninterruptible power supplies (UPS), and other industrial applications.
Figure 46 shows a simplified schematic of the AMC1303Mx in a typical frequency inverter application as used in
industrial motor drives with shunt resistors (R_SHUNT) used for current sensing. Depending on the system design,
either all three or only two motor phase currents are sensed.
