摘要
介绍了一种借助单片机和PC机构成的开关电源功率因数分析系统。由高速ADC、准DMA控制器、8751和伪非易失性RAM等构成的测量仪便于现场测量,测量完毕,允许断电搬动,再与PC通信,由PC完成复杂的数据后处理。该系统同时也解决了开关电源起动。
A measuring and analysing system for power factor of switching power supply, based on MCS 51 and PC, is discussed. The measuring sub system consists of high speed ADC, quasi DMA controller, Intel 8751 and quasi non volatile RAM. And it is convenient for field measuring. After measuring, it can be moved to communicate with a personal computer,by which the measured data are processed. The system can also be used for dynamic process of switching power supply such as start up, sudden load changing,etc.
