Discussion on Synchronization Phenomena in Star-Coupled Oscillators using Distorted Wave Theory

摘要

In the Wien-brdige oscillators star-coupled by one resistor, it has been reported that we can see the synchronization phenomena with in-phase or with ±120° phase shift. However, the reason why such phenomena are observed is still unclear. In this report, we discuss the synchronization phenomena in such systems by investigating the power consumption of the system using the distorted waves with fundamental frequency component and third harmonics component. The results suggest that the harmonics component can govern the synchronization phenomena, and why 120° phase shift is stably excited.
