Abstract
This paper introduces a high power dc testing platform for components test of ITER poloidal field converter prototype. The platform is composed of four phase-controlled rectifiers in parallel with the same direction and output up to rated 120 kA long pulse and 400 kA maximum impulse dc current. In this paper, the circuit model is built and circuit analysis is performed to observe the dynamic behaviors. Due to the feature of strong coupling among paralleled branches, two different control strategies are compared, which respectively are decoupling control and dual closed-loop control. Two operation modes, long pulse model and impulse model adopt their own strategy. Experiments results are performed and the operation modes make an agreement with the theoretical analysis.
