A SHARED PCB CONCEPT THAT INTEGRATES BOTH TELECOM HYBRID DC RECTIFIER (-48V) AC/DC CONVERSION AND AN INVERTER FOR DC/AC CONVERSION TECHNOLOGY.

This paper explores the challenges associated with the traditional multiple-system approach in telecommunication exchange premises and presents opportunities for integrating both rectifier and UPS systems within a single hybrid power cabinet. With the increasing recognition of renewable energy sources, such as solar photovoltaics and wind energy—primarily generating DC power, there is a growing need to combine these with the prevalent AC systems in existing infrastructures. A hybrid approach that merges both DC and AC system designs could yield significant advantages in terms of efficiency, flexibility, and cost-effectiveness. This research focuses on the design strategies, governance approaches, and performance evaluations of systems that integrate both DC and AC components to cater to the specific requirements of telecommunication equipment, including CISCO Switches & Aggregator, OLT/FTTH, IGW, and TX DWDM Core networks equipment. The primary objective is to create a unified and streamlined power solution for both AC and DC loads within the same enclosure. The anticipated outcome of this research is the development of a combined technology rectifier (DC output) and inverter design on a single PCB board. This integrated system architecture aims to reduce energy conversion losses, improve operational efficiency, and enhance flexibility in power management. The product addresses a longstanding issue about the space problem at telecommunication exchanges; both systems can be contained within one cabinet for simultaneous power supply. Therefore, this project looks forward to an improvement of the network with a better assimilation of the data from the two systems in an efficient way.
