Abstract
Abstract—We develop a robust controller for parallel dc–dc buck converters by combining the concepts of integral-vari-able-structure and multiple-sliding-surface control. The advan-tages of the scheme are its simplicity in design, good dynamic response, robustness, ability to nullify the bus-voltage error and the error between the load currents of the converter modules under steady-state conditions, and ability to reduce the impact of very high-frequency dynamics due to parasitics on the closed-loop system. We describe a method for determining the region of existence and stability of the sliding manifolds for such parallel converters. The results show good steady-state and dynamic responses. Index Terms—Closed-loop system, integral-variable-structure, load currents, multiple-sliding-surface control, parallel converters, I.
