Three phase sine wave generator circuit diagram generates three sine waves. Each sine wave output can be seen easily at the output points. You can use oscilloscope to see sine waves at three output. Three phase sine wave generator can be used to generate reference signal in three-phase sine wave inverter to obtain sinusoidal pulse width modulation for three-phase sine wave inverter. you can also adjust frequency by adjusting values of components used in this circuit diagram. I have posted many articles on pure sine wave inverter. You can check following articles:
Circuit diagram of three-phase sine wave generator:
