three phase sine wave generator



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:

Three output taps can be used to see output sin waves produced by this circuit diagram of three-phase sine wave generator. Three phase sine wave generator have many applications in industrial devices. Resistors and capacitors values can be adjusted to change frequency of three-phase sine wave generator. single pole single through switch is used to turn on or turn of circuit. 9 volt battery is used to power this circuit. List of components are given below.
