In general, conventional DC-DC converters are preferred due to their simple structure. However, they may also cause various problems such as a limited voltage transfer gain due to the effect of parasitic components and power switches.It must be also noted that in conventional converters, an increasing intended output voltage significantly contributes to a higher duty ratio, thus causing a higher number of switching losses for them. Luo converters with a very high step-up ability thanks to the voltage lift and super lift method can be used to cope with the setbacks of conventional converters. The super-lift Luo converter utilizes super-lift method that allows a high output voltage gain in geometric progression for high power applications. It also reduces current and voltage ripples and offers a low switching element loss, high output voltage and high power conversion efficiency compared to other conventional DC-DC converters. The present study focuses on the design and analysis of transformer-less high voltage gain super-lift Luo converter for single phase grid tied systems. The output voltage durability of positive output elementary super-lift Luo converter was used as a performance criterion.
