The paper presents the development and implementation of two stage LCL boost converter using fuel cell as an input source in renewable energy system applications, as there are many advantages of using fuel cell instead of using DC as an input source. At Constant input voltage SRC with LCL pattern can preserve Zero Voltage Switching (ZVS) for wide-ranging load discrepancy. For that reason, two stage configurations by means of a zero-voltage Transition (ZVT) with boost face step chased by the Series Resonant Converter in LCL configuration with capacitive output filter. Two stage boost SRC with LCL configuration for capacitive output filter application is having no duty loss, efficiency, lesser transformer turns ratio, lesser problems of ringing in the output rectifier circuit, difficulty of output rectifier, and very narrow duty cycle. Fuel cell is used as an input source due to its advantages against battery operated systems namely cleanliness, higher efficiency, cost effectiveness etc.
