**5. Conclusions**

This paper evaluates the 14 DC-DC boost converters' efficiency, number of components, and stability. The significance of choosing a converter based on load and source requirements is evaluated. The importance of voltage gains and voltage stress factors when connecting solar PV to the grid is discussed. In addition to the non-isolated step up, interleaved and coupled inductors' reliability with respect to solar PV system applications are outlined. The stress on the switches is reduced by coupled inductor with the ZVS operation system to reduce grid instability and synchronization drawbacks. Each converter importance is fully discussed in this review. Microgrids with solar PV will significantly increase the flexibility of the power system, but to make it reliable, it is necessary to choose the proper converters based on corresponding ratings. Selecting a suitable Converter linking PV source and Dc link bus enhances system performance. In addition, the bidirectional interleaved switched capacitor DC-DC converter implemented in grid connection helps reduction of capacitor voltage stress is discussed in this review. This further extends to by interleaved converter use in diminishing the current ripples at low voltage. Even though the converters pose the following merits, many constraints still need to be resolved, such as exceeding duty values to 50% and linear increases of switch voltage stress with increasing duty cycle.
