Abstract
Parallel power rectifier cabinets can increase the capacity of excitation system while may cause serious current unbalance problems among cabinets or thyristors. In this paper, the design of intelligent current-sharing controller (ICSC) based on infineon micro controller unit (MCU) XC164 and field programmable gate array (FPGA) is discussed in detail. The fuzzy self-adaptive PID control algorithm is adopted to slightly adjust the firing pulse for realizing current-sharing among parallel thyristors and thereby among parallel cabinets. The simulation results attest the validity of the design.
