Sliding Mode Control of LLC Resonant DC-DC Converter for Wide output voltage Range in Battery Charging Applications

asghar taheri; Nader Asgari

Volume 2, Issue 2 , April 2019, , Pages 127-136

https://doi.org/10.22111/ieco.2018.27333.1096

Abstract
  In this paper, a sliding mode control of LLC resonant dc-dc converter in low voltage and high current application is presented. The proposed controller operates at two fixed switching frequencies to the battery charger of electric vehicles. In resonant converter, because of the soft switching process, ...  Read More
