Research on the Trigger Angle Adjustment Study of Thyristor Rectifiers Adapted to Pulsed Alternator

This paper focuses on the trigger angle adjustment of thyristor rectifiers adapted to pulsed alternators. Firstly, the working principles of the pulsed alternator power system driving electromagnetic rail load with diode‐type power converter and thyristor‐type power converter are compared. Then, the matching problem between the multiphase pulsed alternator and the thyristor pulse power converter is discussed, and the influence of the load and the mutual inductance of the machine on the adjustment range of the thyristor triggering angle is deeply analyzed. On this basis, a trigger angle adjustment method is proposed to apply to the interference of a strong magnetic field environment, and the constraints to be satisfied to ensure its normal operation are analyzed. Finally, an experimental platform for pulsed power supply based on a multiphase air‐core pulsed alternator is constructed, and relevant experimental research is carried out to provide reference for the further engineering application of the pulsed alternator.
