In this paper, a method is presented to design a minimum order compensator for a PWM buck converter with voltage-mode control that will reduce the closed-loop output impedance to match a specific transfer function. The transfer function for the compensator is rigorously developed. It is shown that a third-order compensator is sufficient to achieve a closed-loop output impedance represented by a first-order transfer function. The method is applied to an example, in which the hardware of the dc-dc converter is realized and tested to verify compliance to system requirements.
