A Quadratic High Step-up DC-DC Boost Converter Based on Coupled inductor with Single Switch and Continuous Input Current

In this paper, a novel quadratic high step-up DC-DC boost converter established on coupled inductor with single switch is introduced. The operation fundamentals of the presented converter are discussed and a simulation test has been carried out to verify validity of the presented converter. The presented converter is compared with other quadratic topologies in criteria as number of elements, voltage stress on switch and voltage gain. The proposed converter benefits from continuous input current and therefore, is applicable for renewable energy applications.
