Abstract

Abstract: The power supply of electronic equipment is significant and have important function in electronic field. In this paper, a detection system of switch power supply based on DSP is introduced. The system can detect the duty-ratio of capacity value, inductance value, resistance value, output voltage value, diode voltage drop and current pulse-width modulation chip on PCB of switch power supply. Consequently, it finishes the real-time detection on PCB and it is significant to research the fault analysis of switch power supply. The schematic diagram and the outside circuit schematic diagram based on DSP is given in the paper. In the meanwhile, the system accomplishes the data selecting and setting of lower computer by using LabVIEW upper computer. The system has the universality to electrical industry.
