Abstract :
This paper presents the process of designing and manufacturing a high-current line-commutated rectifier, which consists of six high current valves. Every valve is constructed through the parallelization of the four thyristors. The design of the physical structure, the placement of busbars, and the arrangement of parallel thyristors are made using an innovative technique so that the current flows equally between them. To ensure equal flow distribution, in addition to the design of hardware structure and the use of suitable methods for simultaneous and accurate triggering of parallel thyristors, a new control technique based on the temperature measurement of each thyristor is proposed. Finally, the experimental results of a 170V, 4000A rectifier are presented to verify the proposed hardware design and control method.
