Methodology for Design and Static–Dynamic Analysis of Current Source Rectifiers: Comparative Evaluation and Experimental Validation

Among the converters currently used for AC-DC conversion, diode rectifiers (DR) and voltage source rectifiers (VSRs) are the most common due to their availability, cost, and efficiency. However, current source rectifiers (CSRs) offer several advantages, including short-circuit protection, no requirement for pre-charging, step-down characteristics, minimal output current ripple, and the avoidance of DC bus capacitors. These benefits can reduce overall size and enhance power quality, but CSRs are typically associated with high conversion losses. Recent advancements in applications that could benefit from the CSRs advantages, and new devices that improve their efficiency, have brought renewed interest to this configuration. Introducing a novel methodology for static and dynamic analysis, this thesis sets out a new approach of design parameters of CSR components, modulation schemes, losses analysis, modelling, and control strategies validating these innovative methodologies and system optimization in experimental investigation. Additionally, a comparison with other topologies is presented, demonstrating that in certain applications and conditions, CSRs are an attractive choice. Although the thesis present novel methods of design, static and dynamic analysis, it is not focusing on a specific aspect of CSRs but provides an overview of the topic and its state-of-art, offering practical insights for engineers.
