| Abstract: | The design and realization of long pulse integrator based on DSP (Digital Signal Processing) technology are studied in this paper.Through an in-depth study of analog integrator,the theoretical analysis of real analog integrator with drift, nonlinear error and capacity Leakage is given in detail. By using chopper and digital signal processing, a long pulse integrator without drift, nonlinear error and capacity leakage is designed and developed,which have been used in measuring diagnostic signal on Tokamak.The reliable signals are obtained with them in the experiment on HT-7 superconducting Tokamak. |
