摘　　要：主要介绍一种基于单片机的开关电源并联模块供电系统的工作原理、硬件组成模块的电路实现和软件设计。提出了基于C8051F020为控制核心的开关电源并联模块供电系统设计,实现了两个额定输出功率均为16W,输出电压为8V的DC/DC模块并联供电。该供电系统的两个并联模块的输出电流之和可在一定范围内变化且可自动分配两模块的电流,具有负载短路保护功能,供电效率为85%左右。This paper mainly introduces a kind of parallel switching power supply based on single chip,including its wo[king prin ciple,realization of hardware module circuit and software design.This paper puts forward a parallel switching power supply system design with the control core based on C8051F020,and designs a DC/DC module parallel power supply with two rated output power are all 16W,output voltage are 8V.The output current of two parallel module in the power supply sys tem can be in a certain range,and two modules can be current distribution.Moreover,the system with a protection function of load short circuit,the power supply efficiency is about 85%.
