Abstract	In microgrids, distributed generators that cannot be dispatched, such as a photovoltaic system, need to control their output power at the maximum power point. The fluctuation of their output power should be minimized with the support of the maximum power point tracking algorithm under the variation of ambient conditions. This paper presents the design and implementation of a high gain DC boost converter (HGDC Boost Converter) with an improved perturb and observe maximum power point tracking algorithm for photovoltaic applications. The proposed converter achieves a high step up ratio, reaching a voltage gain of 10, while maintaining high efficiency and low component count. Compared to traditional methods, the enhanced perturb and observe algorithm provides faster dynamic response and reduced power oscillations around the maximum power point under rapidly changing environmental conditions. To validate the performance of the proposed converter and MPPT algorithm, simulations results are provided, demonstrating the effectiveness of the proposed solution for photovoltaic systems.
