Abstract :
A unified model including feed-forward gains to derive the control-to-output transfer function of peak current-mode controlled PWM dc-dc converters for CCM is presented. The control-to-output transfer functions for peak current-mode controlled PWM dc-dc buck-boost, boost, and buck converters are derived and illustrated for selected values of perturbation ratio using MATLAB. The proposed model is experimentally verified for peak current-mode controlled buck converter operating in CCM.
