Novel high-gain boost converter with experimentally validated ADRC control technique for renewable energy applications.

In this paper, a switched capacitor-based high-gain boost converter is designed that may be used for high-voltage applications. The suggested topology uses two capacitors that get connected in series or parallel for charging and discharging with the help of switches. The primary function of switches is to switch between three duty ratios that describe the converter’s benefit in achieving high voltage gain without employing an individual high-duty ratio. The examination of steady-state characteristics and voltage gain using three alternative duty ratios is described. An ADRC-based controller has been designed for the proposed circuit that is able to regulate the output in the presence of various types of disturbances. A detailed loss analysis has been performed by calculating the conduction and switching losses of MOSFETs and diodes. [ABSTRACT FROM AUTHOR]
