The isolated modulator allows direct measurement of motor phase currents in power inverters. In operation, the HCPL-7560 Isolated Modulator (optocoupler with 3750 VRMS dielectric withstand voltage rating) converts a lowbandwidth analog input into a high-speed one-bit data stream by means of a Sigma-Delta (Σ∆) over-sampling modulator. This modulation provides for high noise margins and excellent immunity against isolation-mode transients.
