“…The Buck-Boost converter shown in the Figure 6 is a type of DC-DC converter that regulates the output voltage by providing an output voltage higher or lower than the input voltage, depending on the application's requirements. It combines the properties of both Buck and Boost converters and can thus be used as an ideal transformer to produce a required output voltage from an input voltage along a reverse polarity, diode for safe operation [15][16][17][18]. There are, therefore, two possible configurations for the converter, and by applying Kirchhoff's laws to each the equations that define it can be extracted for the continuous conduction mode [19].…”

“…Moreover, a comprehensive overview of various types of electronic power converters and their specific applications in renewable energy systems, such as solar, wind, and photovoltaic energy is presented in [14]. An optimized technique that utilizes a combination of the steepest gradient method and a step-size adaptation technique to enhance the performance of MPPT was presented in [15] and, [16] focuses broadly on the utilization of a multi-cell converter to optimize the MPPT of a solar panel that can provide more advantages compared to singlecell converters.…”

This article delves into the hardware implementation of a buck-boost converter on a Texas Instruments C2000 board, tailored for impressed current cathodic protection to safeguard submerged metal structures against corrosion. Impressed current cathodic protection is vital for combating corrosion in buried or submerged metal structures, where a reliable power supply is crucial. The use of solar energy captured by photovoltaic panels emerges as an environmentally sustainable and economically viable solution for this critical application. The paper examines the design, hardware implementation, and system performance, focusing on the integration of the Texas Instruments C2000 board which is, pivotal for the automation and

“…It is obvious from ( 12), (13), and ( 14), that each cell shares a portion of the output load based on the internal resistance, the open circuit voltage and the total load. For IPOP structures with the same type of converter cells, (in ideal conditions) it can be realized from equation (12) that the output power of each cell is equal. Measurements results for load sharing between cells are shown in Table 1.…”

“…Multicell structures have been used in various studies but not primarily for energy efficiency improvement. Arezki Fekik et al [12] proposes a three-cell DC to DC structure for Off-Grid PV systems for improved robustness using an ISOS structure but the study does not include an experimental verification and although simulation results are promising in terms of the maximum power point tracking (MPPT) function, the efficiency is not validated. Furthermore, the reliability of the three-cell DC to DC structure is reduced since failure of one of the three cells leads to overall system failure.…”

Multicell Power Supplies for Improved Energy Efficiency in the Information and Communications Technology Infrastructures

The rapid growth of the Information and Communications Technology (ICT) sector requires additional infrastructure, such as more micro-datacenters and telecom stations, to support the higher internet speeds and low latency requirements of 5G networks. The increased power requirements of the new ICT technologies necessitate the proposal of new power supplies, in an attempt to support the increase in energy demand and running costs. This work provides an in-depth theoretical analysis on the losses of the individual stages of commercially available PSU and proposes a new multicell PSU, the buck PFC converter, which offers a higher overall efficiency at varying load levels. The theoretical results are verified using simulation results, via a PSIM Thermal Module, and using experimental data. The results indicate that multicell structures can improve the overall PSU efficiency by 1.2% at 50% rated power and more than 2.1% at full power. Finally, taking into consideration the economic implications of this study, it is shown that the proposed multicell structure may increase the PSU costs by 10.78%, but the payback period is in the order of just 3.3 years.

The rapid growth of the Information and Communications Technology (ICT) sector requires additional infrastructure, such as more micro-datacenters and telecom stations, to support the higher internet speeds and low latency requirements of 5G net-works. The increased power requirements of the new ICT technologies necessitate the proposal of new power supplies in an attempt to retain the increase in energy demand and running costs. This work provides an in-depth theoretical analysis on the losses of the individual stages of commercially available PSU and proposes a new multicell PSU, Buck-PFC converter, which offers a higher overall efficiency at varying load levels. The theoretical results are verified using simulation results, via PSIM Thermal Module, and using experimental data. The results indicate that multi-cell structures can improve the overall PSU ef-ficiency by 1.2% at 50% rated power and more than 2.1% at full power.
