摘要：Nonlinear phenomena and the control method of the bi-directional DC-DC converter in different operating modes are studied to solve the problem of unstable operation of the bidirectional DC-DC converter in a DC microgrid. The piecewise switch model is built by analyzing the topology and the working process of the bi-directional DC-DC converter as well as employing Matlab/Simulink software. The evolution of the bi-directional DC-DC converter from steady to bifurcation and chaos is got by simulating the piecewise switch model with reference current and output voltage as bifurcation parameters. Finally, the resonant parametric perturbation is applied to control the chaos in bi-directional DC-DC converter, and thereby the stability of the bi-directional DC-DC converter in a DC microgrid has been improved.
