Relationship Between Circuit Parameter and Performance of Cuk Converter in Wind Power System

Wind energy, which is clean and abundant, is attached great importance to and becomes the fastest developing renewable energy. However, the randomness of wind energy brings a series of technical problems for new energy power generation. It is of great significance to study how to rationally apply power electronic devices to ensure the steady-state conversion of electrical energy in wind power system. Considering the engineering application of Cuk converter to solve the stabilized voltage problem in the wind power system, this paper mainly studies the relationship between circuit parameter and performance of Cuk converter. The switching current and the output voltage ripple are taken as a measure of system performance main indicators. The operating principle of the Cuk converter is analyzed and the mathematical model of the parameters, the switching current and the output voltage ripple are set up. The results show that the system can meet the expectation index and output stability by controlling the circuit parameters. It provides a theoretical basis for the component selection of Cuk converter that meets the performance requirements of wind power system. Thus, it provides a feasible method for renewable energy utilization efficiently. The detailed simulation results and experimental results verified the correctness of the theoretical analysis.
