Desenvolvimento de um conversor de baixo custo para acionamento de motores monofásicos

Abstract

This research presents a low-power converter for single-phase machines, with the aim of reducing costs and increasing efficiency in retrofit applications. Single-phase motor appliances consume a significant portion of energy, but their low efficiency often results in energy waste. To address this issue, a dedicated converter can replace the current capacitors used in single-phase motors, improving efficiency and reducing energy consumption. The study also includes a cost comparison between single-phase and three-phase motors, to demonstrate the feasibility of the proposed approach in terms of long-term cost savings and improved energy efficiency. Overall, the results of this study suggest that the low-power converter presents a promising solution for improving energy efficiency and reducing costs in single-phase motor applications.
