Introduction: Fixed-point is a great thing, but the coding can be a bit challenging. However, after finding some methods for fixed-point programming, we can still understand, master, and apply it. After all, floating-point microcontrollers are expensive, while fixed-point microcontrollers are quite affordable. The author’s first microcontroller supported floating-point, and the coding mindset has always been … Read more
Abstract This paper proposes a closed-loop control scheme for the LLC resonant converter based on a Digital Signal Processor (DSP), aimed at optimizing the dynamic response of the converter and improving system stability. By designing appropriate control strategies and feedback loops, combined with the characteristics of the LLC resonant converter, efficient and precise power conversion … Read more
Tang Jianqiang, Zhou Fengxing, Shen Chunpeng (Wuhan University of Science and Technology, School of Information Science and Engineering, Wuhan, Hubei 430081) Abstract: In response to the premature failure of 12 V on-board battery power systems, a battery condition monitoring and intelligent control system based on μC/OS-II has been designed. This system integrates flyback switch power … Read more
