Abstract :
This paper proposes a novel fixed-frequency sliding mode (SM) controller of buck converters in CCM (continuous conduction mode), which almost holds the advantage of robustness and fastness of SM control. The design method of a new SM controller for buck converter is given. Simulation and experimental results verify the validity and feasibility of the fixed-frequency modulation method in Buck converter with SM.
