Abstract

The effect and design criteria of the input filter for buck converters with peak current-mode (PCM) control are researched using a novel system block diagram. With this diagram, a novel current loop transfer function is proposed to derive the design criteria that apply to designing the input filter. However, the input filter that is added to reduce electromagnetic interference will significantly change the dynamic property of the PCM-controlled buck converter. Therefore, the induced effect due to the input filter is examined. Finally, experimental results prove the accuracy of this deduction in both the circuit simulation and the circuit experiment.
