Abstract

Abstract

To meet the requirement of continuous discharge in the integrated system of high power pulse power supply a repeatitive frequency water-cooled inductor for the system was developed. In the system, the water-cooled inductor can not only adjust the current waveform of the power supply, but also play an isolation role. The repeatitive frequency water-cooled inductor can withstand high voltage, large current, charge interval period of 6 seconds, and can work continuously for 10 times of discharge capacity. To meet the requirement of continuous discharge, deionized circulating water is used to cool the inductor. Taking the single module energy of 334 kJ, inductance of 30 μH, and current of 100 kA as an example, the design and analysis are carried out to establish the temperature field simulation model of the inductor, and analysis is made on the transient characteristics of the internal temperature of the inductor through ANSYS simulation software. The results show that the inductor is well cooled by deionized water, and the maximum temperature of the inductor reaches 47 ℃ after each operation, and the temperature of the inductor recovers to 41 ℃ before the next operation point. At the same time, the inductor passes the 112 kA electrodynamic test without circulating water. The experimental results agree well with the theoretical analysis, and the inductor runs stably, which verifies the correctness of theoretical analysis and design.
