Audio-susceptibility of the inner-loop of peak current-mode controlled PWM DC-DC buck converter in CCM
A complete block diagram including feedforward gains to derive the audio-susceptibility for the inner-current loop of peak current-mode controlled PWM dc-dc converter operating in continuous conduction mode is proposed. Audio-susceptibility transfer functions without and with feed-forward gains along with required power-stage transfer functions are derived for peak current-mode controlled PWM dc-dc buck converter. The derived audio-susceptibility transfer functions are illustrated for given values of perturbation ratio using MATLAB.
