Abstract :
This paper presents analysis of peak current mode control for a buck converter operating in continuous conduction mode. The current feedback loop with slope compensation is analyzed. The mathematical modeling with control to output transfer function and stability analysis of the converter based on this transfer function is also presented. The digital implementation of peak current mode control with feedback compensation is described. Simulation results and experimental observations are shown for a buck converter with peak current mode control operating with 100V input voltage and 0-95V, 100A output.
