Abstract
Relative stability of the inner-current loop with slope compensation for peak-current mode controlled PWM dc-dc converters operating in CCM is analyzed. Expressions for required compensation slope and control current level to achieve a specified margin of stability are derived. Design procedure and Saber Sketch simulation results for a buck converter with the inner-current loop are presented to validate the theory presented.
