Title Design of Mobile Power Supply Based on Microprocessor
Abstract
With the development of society informatization and electronic technology, using a variety of digital products are more and more frequent in people's daily life and production, in order to satisfy the long-time power supply demand for electronic equipment, we need to use mobile power supply. This paper uses AT89C51 MCU to realize the design and simulation of mobile power supply circuit, based on polymer battery charge and discharge of 5V implementation. Circuit mainly includes the lithium battery charging circuit, DC-DC circuit, protection circuit and a power display circuit of polymer composition, pided into hardware design and software design part. The main idea of design is to realize the high efficiency conversion circuit, on the basis of implementing functions as concisely as possible. The mobile power supply has the advantages of high conversion efficiency, and has good performance and load regulation.
