Enhancing Energy Efficiency in Indian Telecom Networks: Evaluation of Multi-Level Inverter Architectures and THD Reduction Techniques

Abstract The increasing demand for energy-efficient communication a system has led to the widespread use of inverters in telecommunication networks for power storage and supply. While H-bridge inverters are not commonly employed for data transmission, they play a crucial role in backup power systems and renewable energy integration. This paper explores the application of multi-level H-bridge inverters in telecommunication networks, focusing on their low harmonic distortion and high efficiency. Various modulation techniques, such as phase-shift PWM, PD, POD, and APOD, are investigated to improve inverter performance. The study also examines the use of transformer-based cascaded H-bridge inverters with reduced switch count for effective voltage conversion. The main objective is to minimize the Total Harmonic Distortion (THD) to achieve better energy efficiency in telecommunication networks. A comparative analysis of THD performance is conducted for single-phase and three-phase inverters at different levels. The proposed 5-level Cascaded H-Bridge (CHB) inverter demonstrates the lowest THD of 23.2%, indicating superior power quality and efficiency compared to other topologies. The findings suggest that advanced multi-level inverter designs, such as the 5-level CHB, Active Neutral Point Clamped (ANPC), and Modular Multilevel Converter (MMC), offer promising solutions for reliable and stable power supply in telecommunication infrastructure. Further research is recommended to explore the practical implementation and control strategies of these advanced inverter topologies in telecom networks.
