The design of real-time monitoring of fast controlled power supply

In the device of Experimental Advanced Super-conducting TOKAMAK(EAST),fast controlled power supply is a multi-inverter system based on phase-shifted technology.To ensure the security and normal operation of the device,a real-time monitoring system should be established.After choosing the hardware and building the fast data acquisition system,the real-time acquisition,display and storage of the voltage,electrical current and control signal of the multi-inverter in this fast controlled power supply is finished,with the use of Labview in this paper.It provides sufficient data for fault diagnosis and forecast of the power system.An experiment based on two modulars of inverter in paralled has been carried out,and the result is satisfied.
