摘要：
Digital linear slope control (LSC) method is proposed to reduce the output voltage deviation during the load transient of a buck converter. The proposed LSC method modulates the slope of the control signal to suppress the output voltage deviation. The LSC method utilizes the information of the output voltage only and is realized simply by adding a few lines to the digital code of the conventional VMC. The mathematical analysis is conducted to prove the feasibility of the LSC method and the algorithms for the LSC method are presented. A 15 V–5 V 100-kHz prototype buck converter was built and tested to verify the performance of the LSC method.
