Industrial electrolytic rectifiers work with high currents (in the order of kilo Amps) and very low DC voltage levels (few hundred Volts). The objective of this paper is to address the lack of proper design tools for the evaluation and selection of high current rectifiers, which are primarily Thyristor-based double-bridge and four-star multi-pulse configurations. Methodologically, the authors propose an engineered quantitative solution based on the reliability, electrical performance, efficiency, and required investment for these rectifiers, specifically configuring the evaluation platform using IEEE Standards 493-1997 and IEEE C57.18.10. The results present a thorough discussion of various rectifier topologies, including standard double-bridge and four-star rectifiers alongside improved designs such as chopper-rectifier, sequential rectifier, and filterless rectifier. The findings conclude that the modular multi-cell technology utilized in chopper high-current rectifiers presents significant advantages over traditional Thyristor-based industrial solutions, highlighting the importance of quantitative evaluation in the selection process.
