Phase tracking three-phase generator


Posted on May 18, 2012

Using a single chip LM324 can, with active R-C networks, reduce the size of a 3-phase waveform generator, and prove useful in compact and stable 3-phase inverters. One quarter of an LM324 is used as a Wien bridge oscillator generating a pure sinusoidal waveform while the remaining parts of the LM324 are used as three 120° fixed phase shifters.

Initially potentiometer R3 should be varied to adjust the loop gain of the oscillator in order to start the oscillator.
