Abstract
In this paper, a dual-conversion online static UPS and Line-Interactive UPS system were modeled and simulated using PSIM software. The components of the proposed design were specified based on pre-defined constrains, and the dynamic behavior of the system was modeled through state-space equations. With the system components characterized, a suitable controller was developed for closed-loop control of the buck and boost circuits. A battery charge management controller was also developed to ensure the robustness of the design. Overall system performance was analyzed under varying load and line conditions. Both systems consistently supply power to the load regardless of the state of the grid, as long as the battery SOC is adequate.
