Bifurcation

Solar inverter bifurcation

We find that this inverter can exhibit multiperiod bifurcation, tangential bifurcation and paroxysmal chaos within certain ranges of control coefficients and other circuit parameters, which will influence the system's stability seriously. Moreover, there are the problems suffering the complicated modeling. . In high-power photovoltaic systems, the inverter with an LCL filter is widely used to reduce the value of output inductance at which a lower switching frequency is required. However, the effect on the stability of the system caused by an LCL filter due to its resonance characteristic cannot be. . Abstract—This paper presents bifurcation and chaos in a PWM current-mode H-bridge inverter. This inverter exhibits various interesting bifurca-tion phenomena.
