| Abstract: | A novel design scheme for SPD immunity testing system is designed based on DSP and LabVIEW.The lower computer of the system takes DSP as a core,which achieves collection of SPD impulse signals of voltage and current through high voltage DC power supply,combination wave generator,and impulsive signal measurement circuit and so on,and transfers data to upper computer through USB bus to be processed.Combining with wavelet analysis technology,upper computer management system takes LabVIEW as development platform and uses its functions of graphic display and communication with Matlab to realize display,analysis and processing of measurement data.Test results show that the system has high precision and good stability,and has a good prospect. |
