Research on a dual step-up Cuk converter for different new energy generation

Due to the discontinuity and instability of the new energy generation in the application process, a dual step-up Cuk converter with low input ripple and low output ripple and high efficiency for different new energy generation based on the reliability of the system power supply is proposed in this paper. The operating principle and the operating process is analyzed, key parameter is designed. Computer simulation has been carried out to verify for a dual step-up Cuk converter with a power of 200W. The management strategy was elaborated to verify the feasibility of the power supply system.
