Design of a Reliable Portable Power Supply Chain for an Embedded System

Abstract

Microcontrollers and electrical circuits are fail in case of low supply voltage. They can switch off, oscillate or do unpredictable things because they complexity. To prevent such scenario additional protection circuits and firmware elements should be added. In this article shows a reliable energy supply chain and proposes solutions to prevent this problem. The research aimed to show various PCB designs for diverse environments and supply voltages. The article deals with battery cells, charging and protection circuits, in-circuit current measurement and USPs.
