Boundary Control Of Dual-Output Boost Converter Using State-Energy Plane, Saad Mekhilef

Saad Mekhilef

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 …
