Abstract

This study proposes a new type of quadratic high-gain boost converter to address the problems of high-voltage switching stress and poor dynamic response of the traditional quadratic high-gain boost converter. The proposed quadratic high-gain boost converter can be operated in inductive current continuous conduction mode and pseudo-continuous conduction mode according to different control modes. Results show that the voltage switching stress when the converter is operated in inductive current continuous conduction mode is reduced by 65% compared with the voltage switching stress when the traditional quadratic high-gain boost converter is used. The dynamic response speed when the converter is operated in pseudo-continuous conduction mode is improved by 35% compared with that when the traditional quadratic high-gain boost converter is used. Moreover, additional control freedom is obtained, thereby reducing the difficulty in the design of the compensator. Finally, the veracity of the proposed theory is verified by building an experimental prototype.
