摘要

A dynamic magnetic measurement system for soft magnetic material based on virtual instrument technology is presented. High frequency AC excitation power supply is adopted to drive soft magnetic material. High speed data transport system composed by FPGA chip ALTERA EP1C12Q240C8N and USB microcontroller Cypress CY7C68013A. The problem of phase-shift of hardware integrator which is difficult to control is solved by digital integration. LabVIEW with powerful data processing capabilities is used to simplifies the hardware structure and improve the testing accuracy and automation level of measurement. The paper also points out problems of digital integration and gives a solution.
