Abstract
This paper studies intermittency instability and its control in parallel converters. By numerical simulation, the intermittent subharmonic and chaos are captured with coupled interference signal, their characteristics are described by bifurcation diagrams as parameter varies. Then the paper proposes control methods and it is proved effective by the comparison of power spectrums. The conclusion can help engineer to explain the inherent irregular motion in vehicle, and design more stable power electronic supplies.
