本作品是基于被广泛应用在小功率及各种电子设备领域的开关电源而设

计的开关电源并联供电系统。系统以C8051F020单片机为控制模块，主要包括恒流恒压产生及采样模块，辅助电源模块，LCD及矩阵键盘模块。设计的系统能够输出8V恒压，功率可达到16W。并根据要求对两路电流进行按比例分配，采用一路恒压源、一路恒流源，通过反馈和均流的方法实现。-This work is based on the widely used in low-power and a variety of electronic equipment in the field of switching power supplies and set

Total switching power supply system in parallel. C8051F020 microcontroller system control module, including constant current generation and sampling module, the auxiliary power supply module, LCD and matrix keyboard module. 8V designed system can output constant voltage, power up to 16W. And in accordance with the requirements of the two current prorated, using a constant voltage source all the way, all the way to the constant current source, through feedback and methods are streams.
