This example generates a 3-phase voltage using three analog output channels. A device with three analog output channels is required, such as a 671x data acquisition (DAQ) device.
A three-phase voltage consists of three sine waves, each 120 degrees apart in phase, each representing a separate voltage varying over time.
Before running the VI, enter the three analog output channels you are using. You can also enter the frequency (Hz) of the output sine wave, and the amplitude of each phase voltage.
Connect the three designated output channels to the inputs of a three-phase device like a three-phase motor. For most applications, you will need to amplify the output of the DAQ device.
Since the 671x devices have an analog output FIFO, you can use FIFO generation. If you do not use FIFO generation, you can select the number of data points per cycle. A higher number of points per cycle results in a purer output waveform.
