A boundary control scheme for dual‐output boost converter (DBC) with enhanced performance using second‐order switching surface is presented in this study. The derivation of the switching surface is performed in state‐energy plane rather than the state‐plane to obtain a general geometrical representation that provides a good dynamic response during start‐up and sudden load changes, achieving steady state in two switching actions. To illustrate the control characteristic and performance, a detailed mathematical analysis is fully developed and compared with other control methods for the DBC. The proposed control was simulated, implemented in a digital signal processor TMS320F2812, and tested using prototype hardware. The results obtained for the DBC show good performance in terms of fast transient response under 50% load change and respectable output DC‐bus balancing.
