Abstract

In recent years, switching frequency of Switched-Mode Power Supplies (SMPS) has been getting higher and digital control circuits are adopted for the purpose of downsizing and weight reduction. In addition, current-mode control has attracted attention because of its advantages: high speed response and high stability. However, it is difficult to realize current-mode control with digital control circuit that needs to grasp current behavior in real time because sampling frequency is not enough high for switching frequency. In this paper, we will propose a novel current-mode digital control method that predict current behavior with output voltage and previous current sampling data of SMPS and prove its effectiveness in simulation.
