Renewable energy generation has experienced lot growth in the last not many years, with close to several billion dollars financing in 2017. Selection of an appropriate converter is one of the challenges since it has an impact on the behavior of the PV (photovoltaic) system. In recent years, many converters have been reported in the literature. This paper presents a review of non-isolated DC-DC converters of voltage enhancers. Relevant review details are presented about the topologies of converters, including boost, hybrid boost, three-level boost, multi-level boost, and three-level hybrid converters that are most commonly used in photovoltaic systems. In the end, there are also several voltage level enhancers that can replace the converters provided in photovoltaic systems. Finally, a comparison is made between the converters in terms of the number of elements used in the circuit and the complexity of controlling the switches in the converters with their advantages and disadvantages being presented in a table. Since the use of multi-level boost converters reduces the switch voltage stress, weight, and cost compared to the conventional mode and as they are also better at higher powers, they have been used significantly in different systems.
