Abstract
Oil and electricity prices have been soaring as the supply of global energy is
increasingly becoming deficient. The limited availability of energy sources have become an
inevitable global problem. With global energy shortage, distributed energy sources such as
photo-voltaic cells, fuel cells, wind energy, micro turbine generators, etc., are now widely
promoted around the world. The renewable energy grid connected power system with
photo-voltaic and fuel cells calls for high step-up and high efficiency DC/DC converters
because the low voltage generated by these energy sources should be boosted to a high
voltage for inverter to feed the AC utility. A transformerless DC - DC high step up
switched inductor converters is used here, which combines the passive and active switched
inductor unit , which has the advantages like high voltage conversion ratio, low voltage
stress across the switches, low conduction loss on switches, and easy to control . Analysis
and comparison of various switched inductor based converter is also done in this paper.
