Synchronization Phenomena in Microgrids With Capacitive Coupling

摘要: Multiple converters connected to a microgrid must have the same clock frequency, else interaction among frequencies may cause beating noise. But frequency equalization is difficult achieve in practice. We show that nonlinearity present all power electronic systems offers an interesting possibility: clocks synchronize spontaneously if appropriate coupling exists converters. further control circuits of receive their supply from intermediate bus microgrid, small ripple voltage across capacitor can minute changes clocks—which result synchronization The desirable periodic achieved over specific ranges capacitance depend on ratios uncoupled state.
