An integrated double input DC- DC buck converter in hybrid energy system

Integration of more than one energy source depends on the power electronic converters is an interesting and challenging task for researchers. In this paper, integrated double input DC to DC converter for low voltage energy source applications is explained. Integrated buck converter which can step down the input voltage according to output voltage required at the load end. The converter is able to integrate different voltages of various energy sources such as solar photovoltaic, wind energy system, fuel cell and diesel etc. of relatively low voltage. The converter is designed considering double input, in which same or different type of two inputs can be used individually or simultaneously. Modes of operation of converter are described in detail, closed loop simulation with a PI controller using MATLAB/Simulink^TM results are presented in detail.
