The Application Reasearch Of Cuk Converter Based On Hydrogen Production By Wind Power

With the rapid development of human society,oil,natural gas,coal and other primary energy depletion,wind energy,solar energy and other new energy has gradually been the world’s attention.Wind energy with its clean and pollution-free,the most widely used,the implication of large and other significant features become the primary choice for renewable energy.But because of the volatility of wind power,instability,affecting the large-scale grid operation.In order to maximize the energy consumption,as the Cuk converter can both boost operation,but also antihypertensive operation.The wind power fluctuations have a strong ability to adapt,which is very suitable for wind power and hydrogen production system.This paper takes Cuk converter as the research object,and makes deep research on its application in wind power hydrogen production system.This paper first introduces the research status of wind power supply system,wind power hydrogen production and its regulation technology and DC / DC converter in wind power generation.Secondly,the load characteristics of the electrolytic cell are analyzed,and the relationship between the electrode configuration and the equivalent circuit is analyzed.The Cuk converter is modeled and the critical conditions of the two operating modes are analyzed.The relationship between the output voltage ripple,the switching current and the component parameters are given.Then,the Cuk converter is simulated and simulated in Matlab / Simulink simulation software.The results show that the simulation results are consistent with the theoretical analysis.The theoretical analysis has reference significance to the component selection of Cuk converter.Finally,based on DSP the experimental device of the Cuk converter is built.The results show that the design of the experimental device is reasonable,to meet the load performance indicators requirements.
