Nowadays, the development of PV (Photo Voltaic)-fed LED (Light Emitting Diode) lighting technology is requires high gain ratios with efficient performance of the converter. The presented converter topology is non-isolated possess high gain voltage with low stress voltage. The design of the modified high voltage gain boost configuration is projected with continuous current at input, which is flexible to control. The conduction, switching loss at the switch, reverse recovery problem and electromagnetic interference are mitigated due to low duty cycle. But to explore the differentiation of their characteristics, advantages and several reasonable evaluations are carried out. The operating principle, theoretical analysis and experimental results of modified high gain step-up converter are provided for PV-fed LED lighting applications to verify the efficient performance in all aspects.
