“…In this paper, the passive devices are assumed to be ideal (no associated losses or the losses there are negligible). Then, the efficiency of the proposed hybrid converter is given by: η = P out P out + P loss (13) where P out is the output power of the proposed hybrid converter, and P loss is the total power loss in the proposed hybrid converter, and it can be calculated using the equations in Table 3.…”

This paper introduces a new hybrid DC–DC converter with enhanced voltage gain and synchronized multiple output capabilities, specifically tailored for smart grid applications. The proposed converter is based on the integration of non-isolated Zeta and Mahafzah converters, comprising a single controlled switch, two diodes, three inductors, and two coupling capacitors. The primary objective of this novel hybrid converter is to improve voltage gain as compared to conventional Zeta and Mahafzah topologies. By achieving higher voltage gain at lower duty cycles, the converter effectively reduces voltage stress on semiconductor switches and output diodes, thereby enhancing overall performance and reliability. A comprehensive examination of the hybrid converter’s operating principle is presented, along with detailed calculations of duty cycle and switching losses. The paper also explores the converter’s application in smart grids, specifically in the context of renewable energy systems and electric vehicles. Two distinct scenarios are analyzed to evaluate the converter’s efficacy. Firstly, the converter is assessed as a DC–DC converter for renewable energy systems, highlighting its relevance in sustainable energy applications. Secondly, the converter is evaluated as an electric vehicle adapter, showcasing its potential in the transportation sector. To validate the converter’s performance, extensive simulations are carried out using MATLAB/SIMULINK with parameters set at 25 kW, 200 V, and 130 A. The simulation results demonstrate the converter’s ability to efficiently supply multiple loads with opposing energy flows, making it a promising technology for optimized grid management and energy distribution. Moreover, the paper investigates the total harmonic distortion (THD) of the grid current, focusing on its impact in smart grid environments. Notably, the new hybrid converter topology achieves a THD of 21.11% for the grid current, indicating its ability to effectively mitigate harmonics and improve power quality. Overall, this research introduces a cutting-edge hybrid DC–DC converter that enhances voltage gain and synchronizes multiple outputs, specifically catering to the requirements of smart grid applications. The findings underscore the converter’s potential to significantly contribute to the advancement of efficient and resilient power conversion technologies for smart grids, enabling seamless integration of renewable energy systems and electric vehicles into the grid.

“…According to [16][17][18][19][20] [21], the use of a maximum power point tracking technique (MPPT) algorithm is also necessary to extract as much power as possible from the solar and wind when its irradiation and speed changes. Existing literarure [22] also dealt about PI controller, MPPT algorithm for multiple renewable energy sources with separate DC-DC converters.…”

<span>To power remote area telecom where grid supplied electricity is unreliable, an alternative exists in the form of renewable energy sources. These sources mainly rely on the weather condition of a particular area for their source of power. To overcome such problem, hybridization of energy sources are prefered. Hybridization of solar-wind systems use a separate converter for each source thus leading to a complex, bulky and less efficient system. This paper presents a single renewable power interface which allows solar and wind sources to supply the load separately or simultaneously depending on the availability of the energy sources. It uses cuk and sepic converter topologies to form cuk-seic interfece. These systems also use battery backup to store excess energy and to make best use of their operating characteristics. Performance comparison between a cuk-sepic renewable power interface with and without MPPT using MATLAB/SIMULINK is presented. A detailed componentwise analysis is also done to calculate best efficient interface. It is found that the cuk-sepic interface with MPPT is efficient. A lab level model for cuk-sepic interface is developed and tested. The experimental results proved the effective operation of a single renewable power cuk-sepic interface with MPPT. </span>
