An integrated multi input DC-DC converter in hybrid energy system

In this study, an integrated double input DC to DC buck-buck boost converter for high/low voltage energy source applications is presented. An integrated buck-buck boost converter which can step down or step up the input voltage according to output voltage required at the load end. A multi input converter can be used instead of single input converters to integrate different energy sources such as solar PV, wind energy system, fuel cell and diesel etc. The converter is designed considering double input, in which same or different type of two inputs can be used individually or simultaneously. The operation modes and the steady state analysis of the converter are delinated. Finally converter behavior observed by using Matlab/SimulinkTM enviornment for closed loop simulation with PI control scheme, the obatinaed results are presented in detailed manner
