In an era where uninterrupted power supply is critical for industrial operations, a groundbreaking approach to enhancing uninterruptible power supply (UPS) systems has emerged from the Federal Institute of Santa Catarina (IFSC) in Brazil. Lead researcher Telles B. Lazzarin and his team have developed a novel design for a single-phase UPS that operates at a high output voltage of 660V and a capacity of 15kVA. This innovation is particularly significant given the increasing demand for reliable power solutions in various sectors.
Traditionally, UPS systems provide output voltages that mirror those found in commercial power grids. However, achieving high output voltages has posed challenges, often leading to costly and complex solutions. The research team’s innovative design circumvents these obstacles by employing a series connection of low-output-voltage modular UPS units. “Our approach allows for the construction of a high-output-voltage UPS using standard modules that can be connected in series,” Lazzarin explained. “This not only simplifies the design process but also significantly reduces costs, making it suitable for a wide range of industrial applications.”
The core principle behind this development involves the serial connection of voltage source inverters (VSIs), which enables the aggregation of voltage from multiple lower-voltage modules. The experimental prototype, which consists of three single-phase modules rated at 220V and 5kVA each, demonstrates the feasibility of this approach. The successful integration of these modules into a cohesive system that meets the 660V requirement showcases a promising pathway for future UPS designs.
This research is likely to have substantial commercial implications. As industries increasingly rely on sensitive equipment that requires stable power, the ability to deploy a cost-effective, high-voltage UPS solution could transform operational efficiencies. “With this technology, we can provide industries with a reliable power source that minimizes downtime and enhances productivity,” Lazzarin added.
The implications of this study extend beyond immediate applications. As energy demands continue to evolve, this modular approach could pave the way for more adaptable and scalable power solutions. By leveraging existing technologies, manufacturers can avoid the pitfalls of developing entirely new systems, thus accelerating the deployment of effective power solutions in various sectors.
This innovative research was published in ‘Eletrônica de Potência,’ which translates to ‘Power Electronics.’ For more information about the work of Telles B.
