Load Current Feedforward Control of Boost Converter for Downsizing the Output Filter Capacitor

Abstract

A boost converter is used to supply high voltage to the load in various industrial applications. Generally, boost converters have a large output filter capacitor to suppress the output voltage variation, and this leads to a considerable increase in the size of the system. In this paper, a load current feedforward control of boost converter is proposed. The proposed methods suppress voltage variation compared to feedback control and enable the reduction of output filter capacity. The simulation and experimental results show the effectiveness of the proposed methods.
