Passive Nonlinear Control Strategy for AC/DC Bidirectional Converter
AC/DC bidirectional converter can realize power bidirectional transmission. And it has become a hot topic in the field of power electronics and micro grid. The traditional control method can not consider the nonlinear characteristics of the converter, so it is difficult to obtain satisfactory dynamic response results. A nonlinear control strategy based on the theory of passive control was proposed in this paper. The effectiveness of the proposed strategy was verified by simulation experiments in Matlab platform. The simulation results show that the proposed control strategy can effectively improve the dynamic response characteristics of the system.
