This work shows a development and implementation of a high current rectifier based on the double star rectifier configuration. The proposed rectifier is controlled by a microcontroller. A routine, which controls the rectified load current, was written in assembly language. This routine implements a PI controller that generates a thyristor gate signal that controls the current flux in the converter’s input. A prototype of 6kW power and 300A current capability was build. Comparisons between the experimental and simulated results show that the mathematical model used to predict the rectifier behavior was adequate.
