用于可再生能源的双开关升压变换器OA

With the promotion of clean and renewable energy sources such as solar,wind,and fuel cells,high voltage gain DC/DC con-verters have been widely studied and applied.A new non-isolated double-switching boost converter that utilizes coupled inductors and switched capacitors is proposed.The converter features high gain,high efficiency,continuous input current,and a common ground for both input and output ports.It effectively minimizes the voltage stress on switching devices and reduces the limitations of switching de-vice selection.Initially,the operating principle and component stresses of the converter in continuous conduction mode are analyzed.Subsequently,the key components of the converter are designed.To validate the theoretical analysis,an experimental prototype is con-structed.Rated at 240 W,the experimental prototype confirms the converter's effectiveness.The maximum efficiency and full load effi-ciency are 98.41%and 92.98%,respectively.
