Abstract

This paper presents experimental results of the designed high-Tc superconducting (HTS) power converting system with multiple GdBCO magnets. The system is tested by various sequential controls of four heater-triggered switches and an electromagnet, which consists of two energy storage magnets (ESMs). The experiments are mainly composed of two modes. The first one is a simultaneously operating mode (Mode1), and another is an alternative operating mode (Mode2). Each two sequences are performed at Mode1 (CS1 and CS2) and Mode2 (CS3 and CS4) for charging the ESMs, respectively. In those experiments, the average pumping rate of each sequence is calculated at about 17.55, 41.26, 10.25, and 25.83 mA/s, respectively. In the discharging test, two sequences are tested. Load energy is calculated from load voltage and current due to the difference between precharged energy to verify which operating mode is more effective. Load energy of each sequence reached about 47.97 and 38.83 J after 2000 s, respectively.
