Spread spectrum modulation for multi-input DC-DC converter

Abstract

This project develops spread spectrum modulation for multi-input buck DC-DC converter, with a low number of components. At the same time, independent power transfer capability is provided for input sources. With the use of a battery without any additional switches the power flow capability has been provided. It is best suited for hybrid energy systems or hybrid electric vehicle / electric vehicle applications. Various functional methods of the proposed topology were provided. Subsequently, a common relationship proposed to be proposed to calculate the critical stimulus calculation of the proposed n-input pug topology. Furthermore, a simple proportional control output is used to regulate the voltage and assign a portion of the power to supply each internal source. The tentry edition was modeled on modeling and simulation modeling in the proteus software to ensure the authenticity of the proposed topology and theoretical concepts.
