CIRCUIT OPERATION (cont'd)
The AC output voltage of the each inverter power module is 2400V line to neutral. With phase
voltages shifted 120° from one other, an output voltage of 4160V between phases is generated. The output
voltage closely approximates a sine wave. This is shown in the output waveform below. This produces a
sine wave motor current with low distortion.
