Abstract

This paper aims to design and analyze a three-phase fully controlled bridge rectifier circuit. The paper first introduces the basic principles and advantages of the three-phase fully controlled bridge rectifier circuit and then elaborates on five key aspects of the design: transformer design, thyristor selection, thyristor protection design, trigger circuit design, and trigger circuit power supply design. During the design process, parameters such as the motor’s rated power, voltage, current, and resistance were considered to ensure that the selection of thyristor parameters and protective measures meet the needs of practical applications. In addition, the paper discusses the design of synchronous transformers, phase selection, the application of the KJ004 trigger circuit, and the design of the trigger circuit power supply. Finally, the circuit was simulated using Matlab simulation tools, the circuit design was optimized, and satisfactory pulse waveforms and output waveforms were obtained by adjusting the experimental time. The research in this paper provides theoretical basis and practical guidance for the optimized design of three-phase fully controlled bridge rectifier circuits.
