A novel zero‐steady‐state‐error (ZSSE) compensation technique based on an accurate small signal model of peak current mode buck converter is proposed for optimising the microprocessors with low power consumption needing high‐definition voltage scaling. This technique eliminates the steady‐state error of output voltage without negatively affecting the transient response. The main parasitic parameters of the buck converter are taken into consideration to design an excellent ZSSE compensation module; the relationships between the parameters of the compensation circuit and parameters of the other parts of the converter have been derived in this study. This technique has been implemented on a prototype. The validity of this method is shown and confirmed by test results.
