This paper presents a study on a three-phase 24-pulse Transformer Rectifier Unit (TRU) for use in aircraft electric power system. Four three-phase systems with 15°, 30°, 45°, and 60° phase shifts are obtained by interconnection of conventional transformers in zig-zag configuration. The system is modeled in details using Simulink (SimPowerSystems). Simulation results are presented and the obtained performance is compared with those of a 12-pulse TRU.
