Abstract

Closed-loop small-signal characteristics are given for a voltage-mode-controlled PWM buck DC-DC converter with a proportional controller for continuous conduction mode (CCM). All parasitic resistances are taken into account. The following characteristics are presented at different values of the equivalent series resistance of the filter capacitor: control-to-output transfer functions, input-to-output transfer functions, and input and output impedances
