New step forward for ITER's poloidal field converters

ITER China

Important to powering the ITER poloidal field magnets, the converter bridge (pictured) and external bypass were delivered by Chinese industry to ASIPP for testing last October. Here, the converter bypass undergoes the short circuit withstand test. (Click to view larger version...)
Important to powering the ITER poloidal field magnets, the converter bridge (pictured) and external bypass were delivered by Chinese industry to ASIPP for testing last October. Here, the converter bypass undergoes the short circuit withstand test.
Following the successful commissioning of the ITER power supply test facility at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP) last December, another exciting step forward has been made in the procurement of ITER's poloidal field converters.

The short circuit tests on the ITER poloidal field converter bridges and external bypass were accomplished successfully on 8 January 2014. In a series of stringent tests, partially witnessed by technical staff from the ITER Organization and the Chinese Domestic Agency, the soundness of the design and manufacture of these key components was demonstrated.

The positive test results achieved in December and January have demonstrated that the components fully meet the design requirements for the poloidal field converters. (Pictured: the external bypass.) (Click to view larger version...)
The positive test results achieved in December and January have demonstrated that the components fully meet the design requirements for the poloidal field converters. (Pictured: the external bypass.)
These tests included the short circuit withstand test, the dynamic current balance test, the prospective fault current test with the intervention of electronic protection, the FSC test with the intervention of electronic protection, and the FSC test without the intervention of electronic protection. The novelty of the component design created specific requirements, far different from similar tests performed in the past. The series tests were characterized by high test current (up to 430 kA) and complicated prospective waveform. Efforts from the engineers from the AC/DC converter team at ITER China resulted in the successful conclusion of all required type tests.

These positive test results—which demonstrate that manufacturing can fully meet the design requirements of the ITER poloidal field converters—pave the way for series production to begin.
