Measurement and Control System of Pulse Power Supply Based on HTSPPT

In order to monitor the discharge characteristics of the pulse power, control the pulse power reliable operation, the pulse power supply control system based on high temperature superconducting pulsed power transformer (HTSPPT) was designed by using modern test technology, virtual instrument and database technology. The system is comprised of single-chip, drive circuit board, voltage and current sensor, data acquisition system and computer. The software uses LabVIEW, ActiveX Date Objects (ADO) technology was used to realize the data interaction between LabVIEW and database, and realizes the storage and query of large amount of data. In this paper, the pulse power supply of two modules synchronous and asynchronous triggering HTSPT is measured and controlled. The experimental results show that the system can accurately trigger the turn-on and turn-off time of IGBT and thyristor and control the discharge of pulse power process. From the synchronous triggering, we can accurately measure the instantaneous current with the half peak pulse width of 1.33ms and the Instantaneous load current peak value of 6.622kA. The voltage of the auxiliary capacitor is 883V. From the asynchronous cooperative triggering, the half peak pulse width is 2.866ms, the peak value of the Instantaneous load current is 4.233kA and the voltage of auxiliary capacitor is 1.1kV.
