A Dual Input DC-DC Circuit Applied to New Energy Power Supply Systems

With the consumption of fossil fuels, new energy is increasingly being applied, with wind and solar energy being typical representatives. Due to its simple structure, multi input DC converters have become an increasingly important part of multi energy joint power supply systems, replacing multiple single input DC converters. Therefore, this paper proposes a dual input Cuk converter, and provides a detailed analysis of its working principle and performance characteristics. Finally, it is verified through computer simulation. The results indicate that the circuit can achieve collaborative power supply between two power sources, ensuring stable output voltage and improving system stability and flexibility.
